OIE BSE RECOMMENDATION FOR USA, bought and paid for by your local cattle dealers i.e. USDA
STATEMENT BY DR. RON DEHAVEN REGARDING OIE RISK RECOMMENDATION
March 9, 2007
“In October 2006, the U.S. Department of Agriculture submitted an application and supporting documents to the World Organization for Animal Health (OIE) to formally request country classification for bovine spongiform encephalopathy (BSE) risk. The OIE undertakes a thorough review process before recommending a risk classification, and then provides an opportunity for all delegate countries to review the recommendations and present comments prior to final adoption of a country’s classification at the OIE’s General Assembly meeting in May.
“While we recognize that a final classification decision will not be made by the OIE until May, we feel it is important to be responsive to questions we are now being asked about the risk classification recommended for the United States. The OIE Scientific Commission has endorsed the recommendation from an OIE expert panel that the United States be classified as “controlled risk” for BSE.
“The controlled risk classification recognizes that OIE-recommended, science-based mitigation measures are in place to effectively manage any possible risk of BSE in the cattle population. This recommendation provides strong support that U.S. regulatory controls are effective and that U.S cattle and products from cattle of all ages can be safely traded in accordance with international guidelines, due to our interlocking safeguards.
“The OIE risk classification process is an essential step in promoting trade and understanding of this disease. We appreciate OIE’s review of our application, as well as its leadership in developing sound, science-based guidelines that will help countries standardize regulations and import requirements. We look forward to the final adoption of this classification, which will be announced at the OIE meeting in May.”

Sample Size Estimate for BSE Ongoing Surveillance
July 20, 2006
Purpose, rationale, and objectives of surveillance
Animal and public health concerns about bovine spongiform encephalopathy (BSE) have led to the establishment of active surveillance programs among other regulatory measures to monitor and prevent disease. Active surveillance for BSE was initiated in the United States in 1990. In response to identification of a BSE-affected imported dairy cow in December 2003, the U.S. Enhanced BSE Surveillance Program was implemented in June 2004. Through these efforts, two cases of BSE were identified through March 2006. Both cases were in beef cattle over 10 years old (born before the feed ban of 1997), one located in Texas and one in Alabama.
Based on data collected in the United States over the last 7 years, including over a half million samples from the Enhanced Surveillance program, the USDA has developed an estimate of prevalence of BSE among U.S. cattle that was extremely low, projected at less than one case per million animals in the standing adult cattle population at the 95 percent confidence level (APHIS 2006a). In addition, the USDA demonstrated that surveillance efforts to date far exceed the World Organization for Animal Health (OIE) “type A” surveillance recommendations. Prevalence is expected to decline as long as mitigation efforts that maintain low risk for introduction and spread of the BSE agent among U.S. cattle are equivalent to or better than those evaluated by the Harvard Risk Assessment (Cohen et al., 2001, 2003).
The principal purposes of ongoing BSE surveillance are:
1. To continue to monitor the BSE status of U.S. cattle.
2. To provide mechanisms for detection of BSE prevalence if it were to increase above 1 infected animal per million adults.
In addition, we aim to meet the objective of conducting ongoing surveillance at a level that meets or exceeds OIE surveillance recommendations. We believe this objective is reached by the following sampling strategy, which is sufficient to detect BSE at 1 infected animal per 1,000,000 adult cattle in the population with a high degree of confidence.
Sample Size to Meet OIE Surveillance Recommendations
APHIS is committed to maintaining BSE surveillance that at least meets OIE guidelines. The OIE surveillance guidelines for BSE recommend a target number of surveillance points for Type A surveillance based on the size of a country’s cattle population. These points are accrued over 7 consecutive years, and are weighted according to the surveillance stream and age of the animal sampled. For a large cattle population, using the design prevalence of 1 case per 100,000 adult cattle and 95 percent confidence, 300,000 total points over 7 years, or 42,857 points per year, are required for Type A surveillance (OIE 2005).
The four surveillance streams identified in the OIE Code are clinical suspects; casualty slaughter; fallen stock; and healthy slaughter. OIE guidelines recommend sampling from at least three of the four surveillance streams. BSE surveillance efforts in the United States have always focused on the three surveillance streams where BSE is more likely to be found – clinical suspects, casualty slaughter, and fallen stock. During the 7 consecutive years prior to March 17, 2006, the United States collected 735,213 BSE samples from these surveillance streams and accumulated 2,973,804 OIE points (APHIS 2006b).
As shown in the calculation below, if the ongoing surveillance plan continues similar sample numbers from these surveillance streams, approximately 10,500 cattle per year would be sufficient to meet the OIE minimum number of sample points for Type A surveillance.
2,973,804 points ÷ 735,213 samples = 4.1 points per sample and 42,857 points required per year ÷ 4.1 points per sample = 10,453 samples per year
Sample Size for BSE Prevalence Estimates
The OIE minimum number of samples as outlined would be sufficient for a design prevalence of 1 case per 100,000 adult cattle. However, in the interest of maintaining confidence in previous BSE prevalence estimates, a more sensitive design prevalence of 1 case per 1 million adult cattle will be adopted for ongoing surveillance. The BSurvE model (Wilesmith et al., 2004) can be used to help estimate the number of samples necessary to achieve this level of detection. This model determines sample point values based on a particular population’s demographics.
The point tables described by OIE surveillance guidelines were designed using the BSurvE model to represent a conservative scenario (e.g., low point value and greater number of samples) of the characteristics of the cattle populations of all of its member countries. These demographic characteristics describe a hypothetic population that culls cattle very rapidly (mean age of approximately 4 years) and results in point values that are lower than the BSurvE model would calculate for cattle in most countries. In the United States, however, demographic data indicate 25 percent of the adult cattle population of approximately 42 million are dairy production type and 75% are percent beef cattle (NASS 2005). While the U.S. dairy population undergoes rapid culling similar to the characteristics used to develop the OIE table, beef cattle generally remain in the herd to a much older age until they no longer produce calves. Because actual U.S. data are available regarding population characteristics, it is appropriate to base the sample size estimates on the points calculated through BSurvE given U.S. demographics (these points are hereafter referred to as “analytical points”). The higher average age at which beef cattle are culled influences the BSurvE output and results in substantially higher point values. Hence, sample values calculated with BSurvE from actual U.S. data result in higher point values than the conservative OIE estimates. Each analytical point calculated by BSurvE corresponds to a single nontargeted sample (Wilesmith et al., 2004).
According to OIE, BSurvE and Cannon and Roe (1982) calculations, the required number of non-targeted samples needed to detect a prevalence of 1 case per million adult cattle with 95% confidence (given a population size of 42 million adult cattle) is 3,000,000, 2,995,730, and 2,891,389, respectively. Conservatively using the value of 3 million, we calculate that we will need to accumulate 428,571 analytical points (with negative results) per year across a period of 7 years to meet this objective. 3,000,000 analytical points ÷ 7 years = 428,571 analytical points per year The prevalence analysis conducted on U.S. surveillance data collected from March, 1999 through March 2006 reports 6,745,010 points resulting from 735,213 samples. The average sample was worth 9.5 analytical points.1 6,745,010 analytic points ÷ 735,213 samples = 9.5 analytic points per sample If USDA maintained an equivalent mix of surveillance streams during ongoing surveillance, then approximately 45,113 samples per year would be required to meet this objective. 428,571 analytical points per year ÷ 9.5 analytical points per sample = 45,113 samples per year However, greater than one half million of the samples from Enhanced Surveillance were collected from fallen stock – the surveillance stream that produced the lowest point values. Sampling efforts can be focused on higher value surveillance streams – clinical suspects and casualty slaughter – with a limited number of samples obtained from the fallen stock surveillance stream. This will substantially increase the average point value per sample. Therefore, we estimate that 40,000 samples collected from these three surveillance streams – with a focus on clinical suspects and casualty slaughter - will exceed the number of points necessary to maintain confidence that prevalence is less than one infected animal per million adult cattle. Further, since the data are analyzed over 7 consecutive years, the estimate of sample size may be adjusted each year as appropriate to assure a robust prevalence estimate.

CORPORATION AND ITS PRESIDENT PLEAD GUILTY TO DEFRAUDING GOVERNMENT’S MAD COW DISEASE SURVEILLANCE PROGRAM
PHOENIX -- Farm Fresh Meats, Inc. and Roland Emerson Farabee, 55, of Maricopa, Arizona, pleaded guilty to stealing $390,000 in government funds, mail fraud and wire fraud, in federal district court in Phoenix.U.S. Attorney Daniel Knauss stated, “The integrity of the system that tests for mad cow disease relies upon the honest cooperation of enterprises like Farm Fresh Meats. Without that honest cooperation, consumers both in the U.S. and internationally are at risk. We want to thank the USDA’s Office of Inspector General for their continuing efforts to safeguard the public health and enforce the law.” Farm Fresh Meats and Farabee were charged by Information with theft of government funds, mail fraud and wire fraud. According to the Information, on June 7, 2004, Farabee, on behalf of Farm Fresh Meats, signed a contract with the U.S. Department of Agriculture (the “USDA Agreement”) to collect obex samples from cattle at high risk of mad cow disease (the “Targeted Cattle Population”). The Targeted Cattle Population consisted of the following cattle: cattle over thirty months of age; nonambulatory cattle; cattle exhibiting signs of central nervous system disorders; cattle exhibiting signs of mad cow disease; and dead cattle. Pursuant to the USDA Agreement, the USDA agreed to pay Farm Fresh Meats $150 per obex sample for collecting obex samples from cattle within the Targeted Cattle Population, and submitting the obex samples to a USDA laboratory for mad cow disease testing. Farm Fresh Meats further agreed to maintain in cold storage the sampled cattle carcasses and heads until the test results were received by Farm Fresh Meats.
Evidence uncovered during the government’s investigation established that Farm Fresh Meats and Farabee submitted samples from cattle outside the Targeted Cattle Population. Specifically, Farm Fresh Meats and Farabee submitted, or caused to be submitted, obex samples from healthy, USDA inspected cattle, in order to steal government moneys.
Evidence collected also demonstrated that Farm Fresh Meats and Farabee failed to maintain cattle carcasses and heads pending test results and falsified corporate books and records to conceal their malfeasance. Such actions, to the extent an obex sample tested positive (fortunately, none did), could have jeopardized the USDA’s ability to identify the diseased animal and pinpoint its place of origin. On Wednesday, February 14, 2007, Farm Fresh Meats and Farabee pleaded guilty to stealing government funds and using the mails and wires to effect the scheme. According to their guilty pleas:
(a) Farm Fresh Meats collected, and Farabee directed others to collect, obex samples from cattle outside the Targeted Cattle Population, which were not subject to payment by the USDA;
(b) Farm Fresh Meats2 and Farabee caused to be submitted payment requests to the USDA knowing that the requests were based on obex samples that were not subject to payment under the USDA Agreement; (c) Farm Fresh Meats completed and submitted, and Farabee directed others to complete and submit, BSE Surveillance Data Collection Forms to the USDA’s testing laboratory that were false and misleading;
(d) Farm Fresh Meats completed and submitted, and Farabee directed others to complete and submit, BSE Surveillance Submission Forms filed with the USDA that were false and misleading;
(e) Farm Fresh Meats falsified, and Farabee directed others to falsify, internal Farm Fresh Meats documents to conceal the fact that Farm Fresh Meats was seeking and obtaining payment from the USDA for obex samples obtained from cattle outside the Targeted Cattle Population; and
(f) Farm Fresh Meats failed to comply with, and Farabee directed others to fail to comply with, the USDA Agreement by discarding cattle carcasses and heads prior to receiving BSE test results.
A conviction for theft of government funds carries a maximum penalty of 10 years imprisonment. Mail fraud and wire fraud convictions carry a maximum penalty of 20 years imprisonment. Convictions for the above referenced violations also carry a maximum fine of $250,000 for individuals and $500,000 for organizations. In determining an actual sentence, Judge Earl H. Carroll will consult the U.S. Sentencing Guidelines, which provide appropriate sentencing ranges. The judge, however, is not bound by those guidelines in determining a sentence. Sentencing is set before Judge Earl H. Carroll on May 14, 2007. The investigation in this case was conducted by Assistant Special Agent in Charge Alejandro Quintero, United States Department of Agriculture, Office of Inspector General. The prosecution is being handled by Robert Long, Assistant U.S. Attorney, District of Arizona, Phoenix.

National Veterinary Services Laboratory (NVSL) Immunohistochemistry (IHC) Testing Summary
The BSE enhanced surveillance program involves the use of a rapid screening test, followed by confirmatory testing for any samples that come back "inconclusive." The weekly summary below captures all rapid tests conducted as part of the enhanced surveillance effort. It should be noted that since the enhanced surveillance program began, USDA has also conducted approximately 9,200 routine IHC tests on samples that did not first undergo rapid testing. This was done to ensure that samples inappropriate for the rapid screen test were still tested, and also to monitor and improve upon IHC testing protocols. Of those 9,200 routine tests, one test returned a non-definitive result on July 27, 2005. That sample underwent additional testing at NVSL, as well as at the Veterinary Laboratories Agency in Weybridge, England, and results were negative.

BSE test options were limited
USDA: In 9,200 cases only one type of test could be used
WASHINGTON (AP)--The U.S. Department of Agriculture acknowledged Aug. 17 that its testing options for bovine spongiform encephalopathy were limited in 9,200 cases despite its effort to expand surveillance throughout the U.S. herd.
In those cases, only one type of test was used--one that failed to detect the disease in an infected Texas cow.
The department posted the information on its website because of an inquiry from The Associated Press.
Conducted over the past 14 months, the tests have not been included in the department's running tally of BSE tests since last summer. That total reached 439,126 on Aug. 17.
"There's no secret program," the department's chief veterinarian, John Clifford, said in an interview. "There has been no hiding, I can assure you of that."
Officials intended to report the tests later in an annual report, Clifford said.
These 9,200 cases were different because brain tissue samples were preserved with formalin, which makes them suitable for only one type of test--immunohistochemistry, or IHC.
In the Texas case, officials had declared the cow free of disease in November after an IHC test came back negative. The department's inspector general ordered an additional kind of test, which confirmed the animal was infected.
Veterinarians in remote locations have used the preservative on tissue to keep it from degrading on its way to the department's laboratory in Ames, Iowa. Officials this year asked veterinarians to stop using preservative and send fresh or chilled samples within 48 hours.
The department recently investigated a possible case of BSE that turned up in a preserved sample. Further testing ruled out the disease two weeks ago.
Scientists used two additional tests--rapid screening and Western blot--to help detect BSE in the country's second confirmed case, in a Texas cow in June. They used IHC and Western blot to confirm the first case, in a Washington state cow in December 2003.
"The IHC test is still an excellent test," Clifford said. "These are not simple tests, either."
Clifford pointed out that scientists reran the IHC several times and got conflicting results. That happened, too, with the Western blot test. Both tests are accepted by international animal health officials.

I wish to ask a question about Bio-Rad and USDA BSE/TSE testing and there inconclusive. IS the Bio-Rad test for BSE/TSE that complicated, or is there most likely some human error we are seeing here?
HOW can Japan have 2 positive cows with No clinical signs WB+, IHC-, HP- , BUT in the USA, these cows are considered 'negative'?
IS there more politics working here than science in the USA?

at approx. 14:00 hours 12/28/04, I had a very pleasant phone conversation with XXXX XXXXX about the USDA and the inconclusive BSE testing problems they seem to keep having. X was very very cautious as to speak directly about USDA and it's policy of not using WB. X was very concerned as a Bio-Rad official of retaliation of some sort. X would only speak of what other countries do, and that i should take that as an answer. I told X I understood that it was a very loaded question and X agreed several times over and even said a political one.
my question;
Does Bio-Rad believe USDA's final determination of False positive, without WB, and considering the new atypical TSEs not showing positive with -IHC and -HP ???
ask if i was a reporter. i said no, i was with CJD Watch and that i had lost my mother to hvCJD. X did not want any of this recorded or repeated.
again, very nervous, will not answer directly about USDA for fear of retaliation, but again said X tell me what other countries are doing and finding, and that i should take it from there. "very difficult to answer"
"very political"
"very loaded question"
outside USA and Canada, they use many different confirmatory tech. in house WB, SAF, along with IHC, HP, several times etc. you should see at several talks meetings (TSE) of late Paris Dec 2, that IHC- DOES NOT MEAN IT IS NEGATIVE. again, look what the rest of the world is doing. said something about Dr. Houston stating; any screening assay, always a chance for human error. but with so many errors (i am assuming X meant inconclusive), why are there no investigations, just false positives? said something about ''just look at the sheep that tested IHC- but were positive''. ...

Executive Summary
In June 2005, an inconclusive bovine spongiform encephalopathy (BSE) sample from November 2004, that had originally been classified as negative on the immunohistochemistry test, was confirmed positive on SAF immunoblot (Western blot). The U.S. Department of Agriculture (USDA) identified the herd of origin for the index cow in Texas; that identification was confirmed by DNA analysis. USDA, in close cooperation with the Texas Animal Health Commission (TAHC), established an incident command post (ICP) and began response activities according to USDA’s BSE Response Plan of September 2004. Response personnel removed at-risk cattle and cattle of interest (COI) from the index herd, euthanized them, and tested them for BSE; all were negative. USDA and the State extensively traced all at-risk cattle and COI that left the index herd. The majority of these animals entered rendering and/or slaughter channels well before the investigation began. USDA’s response to the Texas finding was thorough and effective.

Report on Food & Drug Administration Dallas District Investigation of Bovine Spongiform Encephalopathy Event in Texas 2005
Executive Summary:
On June 24, 2005, USDA informed FDA that a cow in Texas tested positive for Bovine Spongiform Encephalopathy (BSE). Information provided by APHIS was that the BSE positive cow was born and raised in a herd in Texas and was approximately 12 years old. The animal was sampled for BSE at a pet food plant in Texas on November 15, 2004, as part of USDA’s enhanced surveillance program.
http://www.fda.gov/cvm/texasfeedrpt.htm
Texas even had a 'secret' test that showed that mad cow positive;
experimental IHC test results, because the test was
not a validated procedure, and because the two
approved IHC tests came back negative, the results
were not considered to be of regulatory significance
and therefore were not reported beyond the
laboratory.
• A Western blot test conducted the week of
June 5, 2005, returned positive for BSE.

48 hr BSE confirmation turnaround took 7+ months to confirm this case, so the BSE MRR policy could be put into place. ...TSS
THIS highly suspect stumbling and staggering Texas Mad Cow got not test at all, went straight to render ;
FOR IMMEDIATE RELEASE Statement May 4, 2004 Media Inquiries: 301-827-6242 Consumer Inquiries: 888-INFO-FDA
Statement on Texas Cow With Central Nervous System Symptoms On Friday, April 30 th , the Food and Drug Administration learned that a cow with central nervous system symptoms had been killed and shipped to a processor for rendering into animal protein for use in animal feed.
FDA, which is responsible for the safety of animal feed, immediately began an investigation. On Friday and throughout the weekend, FDA investigators inspected the slaughterhouse, the rendering facility, the farm where the animal came from, and the processor that initially received the cow from the slaughterhouse.
FDA's investigation showed that the animal in question had already been rendered into "meat and bone meal" (a type of protein animal feed). Over the weekend FDA was able to track down all the implicated material. That material is being held by the firm, which is cooperating fully with FDA.
Cattle with central nervous system symptoms are of particular interest because cattle with bovine spongiform encephalopathy or BSE, also known as "mad cow disease," can exhibit such symptoms. In this case, there is no way now to test for BSE. But even if the cow had BSE, FDA's animal feed rule would prohibit the feeding of its rendered protein to other ruminant animals (e.g., cows, goats, sheep, bison).
FDA is sending a letter to the firm summarizing its findings and informing the firm that FDA will not object to use of this material in swine feed only. If it is not used in swine feed, this material will be destroyed. Pigs have been shown not to be susceptible to BSE. If the firm agrees to use the material for swine feed only, FDA will track the material all the way through the supply chain from the processor to the farm to ensure that the feed is properly monitored and used only as feed for pigs.
To protect the U.S. against BSE, FDA works to keep certain mammalian protein out of animal feed for cattle and other ruminant animals. FDA established its animal feed rule in 1997 after the BSE epidemic in the U.K. showed that the disease spreads by feeding infected ruminant protein to cattle.
Under the current regulation, the material from this Texas cow is not allowed in feed for cattle or other ruminant animals. FDA's action specifying that the material go only into swine feed means also that it will not be fed to poultry.
FDA is committed to protecting the U.S. from BSE and collaborates closely with the U.S. Department of Agriculture on all BSE issues. The animal feed rule provides crucial protection against the spread of BSE, but it is only one of several such firewalls. FDA will soon be improving the animal feed rule, to make this strong system even stronger.

THE TEXAS GONZALES/PURINA INCIDENT SHOWED THAT 5.5 GRAMS OF RUMINANT PROTEIN WAS FED TO CATTLE ;
FOR IMMEDIATE RELEASE P01-05 January 30, 2001 Print Media: 301-827-6242 Broadcast Media: 301-827-3434 Consumer Inquiries: 888-INFO-FDA
FDA ANNOUNCES TEST RESULTS FROM TEXAS FEED LOT
Today the Food and Drug Administration announced the results of tests taken on feed used at a Texas feedlot that was suspected of containing meat and bone meal from other domestic cattle -- a violation of FDA's 1997 prohibition on using ruminant material in feed for other ruminants. Results indicate that a very low level of prohibited material was found in the feed fed to cattle.
FDA has determined that each animal could have consumed, at most and in total, five-and-one-half grams - approximately a quarter ounce -- of prohibited material. These animals weigh approximately 600 pounds.
It is important to note that the prohibited material was domestic in origin (therefore not likely to contain infected material because there is no evidence of BSE in U.S. cattle), fed at a very low level, and fed only once. The potential risk of BSE to such cattle is therefore exceedingly low, even if the feed were contaminated.
According to Dr. Bernard Schwetz, FDA's Acting Principal Deputy Commissioner, "The challenge to regulators and industry is to keep this disease out of the United States. One important defense is to prohibit the use of any ruminant animal materials in feed for other ruminant animals. Combined with other steps, like U.S. Department of Agriculture's (USDA) ban on the importation of live ruminant animals from affected countries, these steps represent a series of protections, to keep American cattle free of BSE."
Despite this negligible risk, Purina Mills, Inc., is nonetheless announcing that it is voluntarily purchasing all 1,222 of the animals held in Texas and mistakenly fed the animal feed containing the prohibited material. Therefore, meat from those animals will not enter the human food supply. FDA believes any cattle that did not consume feed containing the prohibited material are unaffected by this incident, and should be handled in the beef supply clearance process as usual.
FDA believes that Purina Mills has behaved responsibly by first reporting the human error that resulted in the misformulation of the animal feed supplement and then by working closely with State and Federal authorities.
This episode indicates that the multi-layered safeguard system put into place is essential for protecting the food supply and that continued vigilance needs to be taken, by all concerned, to ensure these rules are followed routinely.
FDA will continue working with USDA as well as State and local officials to ensure that companies and individuals comply with all laws and regulations designed to protect the U.S. food supply.

Experimental BSE Infection of Non-human Primates: Efficacy of the Oral Route

Background:
In 2001, a study was initiated in primates to assess the risk for humans to contract BSE through contaminated food. For this purpose, BSE brain was titrated in cynomolgus monkeys.
Aims:
The primary objective is the determination of the minimal infectious dose (MID50) for oral exposure to BSE in a simian model, and, by in doing this, to assess the risk for humans.
Secondly, we aimed at examining the course of the disease to identify possible biomarkers.
Methods:
Groups with six monkeys each were orally dosed with lowering amounts of BSE brain: 16g, 5g, 0.5g, 0.05g, and 0.005g. In a second titration study, animals were intracerebrally (i.c.) dosed (50, 5, 0.5, 0.05, and 0.005 mg).
Results:
In an ongoing study, a considerable number of high-dosed macaques already developed simian vCJD upon oral or intracerebral exposure or are at the onset of the clinical phase. However, there are differences in the clinical course between orally and intracerebrally infected animals that may influence the detection of biomarkers.
Conclusions:
Simian vCJD can be easily triggered in cynomolgus monkeys on the oral route using less than 5 g BSE brain homogenate. The difference in the incubation period between 5 g oral and 5 mg i.c. is only 1 year (5 years versus 4 years). However, there are rapid progressors among orally dosed monkeys that develop simian vCJD as fast as intracerebrally inoculated animals. The work referenced was performed in partial fulfilment of the study "BSE in primates" supported by the EU (QLK1-2002-01096).

Risk of oral infection with bovine spongiform encephalopathy agent in primates
Corinne Ida Lasmézas, Emmanuel Comoy, Stephen Hawkins, Christian Herzog, Franck Mouthon, Timm Konold, Frédéric Auvré, Evelyne Correia, Nathalie Lescoutra-Etchegaray, Nicole Salès, Gerald Wells, Paul Brown, Jean-Philippe Deslys Summary The uncertain extent of human exposure to bovine spongiform encephalopathy (BSE)--which can lead to variant Creutzfeldt-Jakob disease (vCJD)--is compounded by incomplete knowledge about the efficiency of oral infection and the magnitude of any bovine-to-human biological barrier to transmission. We therefore investigated oral transmission of BSE to non-human primates. We gave two macaques a 5 g oral dose of brain homogenate from a BSE-infected cow. One macaque developed vCJD-like neurological disease 60 months after exposure, whereas the other remained free of disease at 76 months. On the basis of these findings and data from other studies, we made a preliminary estimate of the food exposure risk for man, which provides additional assurance that existing public health measures can prevent transmission of BSE to man.

6. It also appears to me that Mr Bradley’s answer (that it would take less than say 100 grams) was probably given with the benefit of hindsight; particularly if one considers that later in the same answer Mr Bradley expresses his surprise that it could take as little of 1 gram of brain to cause BSE by the oral route within the same species. This information did not become available until the "attack rate" experiment had been completed in 1995/96. This was a titration experiment designed to ascertain the infective dose. A range of dosages was used to ensure that the actual result was within both a lower and an upper limit within the study and the designing scientists would not have expected all the dose levels to trigger infection. The dose ranges chosen by the most informed scientists at that time ranged from 1 gram to three times one hundred grams. It is clear that the designing scientists must have also shared Mr Bradley’s surprise at the results because all the dose levels right down to 1 gram triggered infection.

Finding 2 Inherent Challenges in Identifying and Testing High-Risk Cattle Still Remain
Our prior report identified a number of inherent problems in identifying and testing high-risk cattle. We reported that the challenges in identifying the universe of high-risk cattle, as well as the need to design procedures to obtain an appropriate representation of samples, was critical to the success of the BSE surveillance program. The surveillance program was designed to target nonambulatory cattle, cattle showing signs of CNS disease (including cattle testing negative for rabies), cattle showing signs not inconsistent with BSE, and dead cattle. Although APHIS designed procedures to ensure FSIS condemned cattle were sampled and made a concerted effort for outreach to obtain targeted samples, industry practices not considered in the design of the surveillance program reduced assurance that targeted animals were tested for BSE.
In our prior report, we recommended that APHIS work with public health and State diagnostic laboratories to develop and test rabies-negative samples for BSE. This target group is important for determining the prevalence of BSE in the United States because rabies cases exhibit clinical signs not inconsistent with BSE; a negative rabies test means the cause of the clinical signs has not been diagnosed.
APHIS agreed with our recommendation and initiated an outreach program with the American Association of Veterinary Laboratory Diagnosticians, as well as State laboratories. APHIS also agreed to do ongoing monitoring to ensure samples were obtained from this target population.
Although APHIS increased the samples tested from this target group as compared to prior years, we found that conflicting APHIS instructions on the ages of cattle to test resulted in inconsistencies in what samples were submitted for BSE testing. Therefore, some laboratories did not refer their rabies negative samples to APHIS in order to maximize the number tested for this critical target population. In addition, APHIS did not monitor the number of submissions of rabies negative samples for BSE testing from specific laboratories.
According to the Procedure Manual for BSE Surveillance, dated October 2004, the target population includes:
Central nervous system (CNS) signs and/or rabies negative - sample animals of any age (emphasis added):
a. Diagnostic laboratories –samples submitted due to evidence of CNS clinical signs.
Rabies Negative Samples
USDA/OIG-A/50601-10-KC Page 19 USDA/OIG-A/50601-10-KC Page 20
b. Public health laboratories – rabies negative cases.
c. Slaughter facilities – CNS ante mortem condemned at slaughter, sampled by FSIS.
d. On-the-farm – CNS cattle that do not meet the criteria for a foreign animal disease investigation.
For FYs 2002, 2003, and 2004 (through February 2004), NVSL received 170, 133, and 45 rabies-negative samples, respectively. Between June 1, 2004, and May 29, 2005, the number of samples received for testing increased to 226 rabies suspect samples. The collection sites submitting these samples follow.

We obtained a copy of a memorandum, dated July 13, 2004, that APHIS sent to diagnostic and public health laboratories providing them instructions on submitting samples for cattle showing signs of CNS diseases, but testing negative for rabies. The letter was sent to about 170 State veterinary diagnostic and public health laboratories and discussed the need to submit specimens to NVSL of all adult cattle (emphasis added) that showed signs of CNS diseases, but tested negative for rabies. This directive did not specify the age of the cattle. The Procedure Manual for BSE Surveillance, dated October 2004, specified samples of cattle of any age should be submitted.
We contacted laboratories in six States to determine if it was standard procedure to submit all negative rabies samples to NVSL. We found that, because of the lack of specificity in the APHIS letter and inadequate followup by APHIS, there were inconsistencies in the age of cattle samples submitted for BSE testing. For those States contacted, the following samples were submitted versus tested as negative for rabies.

a/ A Pennsylvania laboratory official said only rabies negative cattle over 20 months of age were submitted for BSE testing. The laboratory did not submit 18 samples for BSE testing because the animals were less than 20 months of age.
b/ Kansas laboratory officials said early in the expanded surveillance program, there was confusion as to the cattle ages that should be submitted for BSE testing. They did not know if cattle should be submitted that were above 20 months or 30 months of age. Of the 16 animals not submitted for BSE testing, 14 were under 20 months of age from early in the expanded surveillance program. The other two animals were not tested due to internal laboratory issues. The Kansas and Nebraska area office officials contacted the laboratory and told the officials to submit rabies negative cattle of any age for BSE testing. The laboratory now submits all rabies negative cattle for BSE testing.
c/ A Wisconsin laboratory official said only rabies negative cattle samples 30 months of age or older are submitted for BSE testing. Of the 11 animals not submitted for BSE testing, 8 were less than 30 months of age. Wisconsin laboratory officials were not certain why the other three samples were not submitted.
d/ Laboratory officials from South Dakota said they did not receive notification from APHIS regarding the submission of rabies negative cases for BSE testing. The section supervisor and laboratory director were not aware of any letter sent to the laboratory. The section supervisor said most bovine rabies tests at the laboratory are performed on calves. We confirmed the laboratory’s address matched the address on APHIS’ letter distribution list. However, there was no evidence that the South Dakota area office contacted the laboratory. The laboratory was not listed on the documentation from the APHIS regional office detailing the area office contacts with laboratory personnel. We contacted the South Dakota area office and were advised that while some contact had been made with the laboratory, the contact may have involved Brucellosis rather than BSE. On May 4, 2005, the area office

advised us they recently contacted the laboratory regarding the submission of rabies negative samples for BSE testing.
e/ Arizona and Mississippi laboratory officials said they submitted all rabies negative samples for BSE testing regardless of the age of the animal.
An NVSL official stated that APHIS is not concerned with rabies negatives samples from cattle less than 30 months of age. This position, however, is contrary to APHIS’ published target population.
Our prior audit recognized the significant challenge for APHIS to obtain samples from some high-risk populations because of the inherent problems with obtaining voluntary compliance and transporting the carcasses for testing. USDA issued rules to prohibit nonambulatory animals (downers) from entering the food supply at inspected slaughterhouses. OIG recommended, and the International Review Subcommittee33 emphasized, that USDA should take additional steps to assure that facilitated pathways exist for dead and nonambulatory cattle to allow for the collection of samples and proper disposal of carcasses. Between June 1, 2004, and May 31, 2005, the APHIS database documents 27,617 samples were collected showing a reason for submission of nonambulatory and 325,225 samples were collected with reason of submission showing "dead."
APHIS made extensive outreach efforts to notify producers and private veterinarians of the need to submit and have tested animals from these target groups. They also entered into financial arrangements with 123 renderers and other collection sites to reimburse them for costs associated with storing, transporting, and collecting samples. However, as shown in exhibit F, APHIS was not always successful in establishing agreements with non-slaughter collection sites in some States. APHIS stated that agreements do not necessarily reflect the entire universe of collection sites and that the presentation in exhibit F was incomplete because there were many collection sites without a payment involved or without a formal agreement. We note that over 90 percent of the samples collected were obtained from the 123 collection sites with agreements and; therefore, we believe agreements offer the best source to increase targeted samples in underrepresented areas.
We found that APHIS did not consider industry practices in the design of its surveillance effort to provide reasonable assurance that cattle exhibiting possible clinical signs consistent with BSE were tested. Slaughter facilities do not always accept all cattle arriving for slaughter because of their business requirements. We found that, in one State visited, slaughter facilities pre-screened and rejected cattle (sick/down/dead/others not meeting business

34 FSIS regulations do not specifically address the designation of an establishment’s "official" boundaries; however, FSIS Notices 29-04 (dated May 27, 2004) and 40-04 (dated July 29, 2004) make it clear that FSIS inspection staff are not responsible for sampling dead cattle that are not part of the "official" premises.
35 APHIS’ area office personnel stated that it was their understanding that some establishments in the State were not presenting cattle that died or were down on the transport vehicle to FSIS for ante mortem inspection. The dead and down cattle were left in the vehicle, if possible. In rare circumstances, dead cattle may be removed from the trailer by plant personnel to facilitate the unloading of other animals.

standards) before presentation for slaughter in areas immediately adjacent or contiguous to the official slaughter establishment. These animals were not inspected and/or observed by either FSIS or APHIS officials located at the slaughter facilities.
FSIS procedures state that they have no authority to inspect cattle not presented for slaughter. Further, APHIS officials stated they did not believe that they had the authority to go into these sorting and/or screening areas and require that the rejected animals be provided to APHIS for BSE sampling. Neither APHIS nor FSIS had any process to assure that animals left on transport vehicles and/or rejected for slaughter arrived at a collection site for BSE testing. FSIS allows slaughter facilities to designate the area of their establishment where federal inspection is performed; this is designated as the official slaughter establishment.34
We observed animals that were down or dead in pens outside the official premises that were to be picked up by renderers. Animals that were rejected by plant personnel were transported off the premises on the same vehicles that brought them to the plant.35
A policy statement36 regarding BSE sampling of condemned cattle at slaughter plants provided that effective June 1, 2004, FSIS would collect BSE samples for testing: 1) from all cattle regardless of age condemned by FSIS upon ante mortem inspection for CNS impairment, and 2) from all cattle, with the exception of veal calves, condemned by FSIS upon ante mortem inspection for any other reason.
FSIS Notice 28-04, dated May 20, 2004, informed FSIS personnel that, "FSIS will be collecting brain samples from cattle at federally-inspected establishments for the purpose of BSE testing." The notice further states that, "Cattle off-loaded from the transport vehicle onto the premises of the federally-inspected establishment (emphasis added), whether dead or alive, will be sampled by the FSIS Public Health Veterinarian (PHV) for BSE after the cattle have been condemned during ante mortem inspection. In addition, cattle passing ante mortem inspection but later found dead prior to slaughter will be condemned and be sampled by the FSIS PHV."

37 FSIS Notice 40-04, dated July 29, 2004.
38 FSIS Notice 29-04, dated May 27, 2004.
APHIS has the responsibility for sampling dead cattle off-loaded onto plant-owned property that is adjoining to, but not considered part of, the "official premises.37 FSIS procedures38 provide that "Dead cattle that are off-loaded to facilitate the off-loading of live animals, but that will be re-loaded onto the transport vehicle, are not subject to sampling by FSIS.
While performing our review in one State, we reviewed the circumstances at two slaughter facilities in the State that inspected and rejected unsuitable cattle before the animals entered the official receiving areas of the plants. This pre-screening activity was conducted in areas not designated by the facility as official premises of the establishment and not under the review or supervision of FSIS inspectors. The plant rejected all nonambulatory and dead/dying/sick animals delivered to the establishment. Plant personnel refused to offload any dead or downer animals to facilitate the offloading of ambulatory animals. Plant personnel said that the driver was responsible for ensuring nonambulatory animals were humanely euthanized and disposing of the carcasses of the dead animals. Plant personnel informed us that they did not want to jeopardize contracts with business partners by allowing unsuitable animals on their slaughter premises.
In the second case, one family member owned a slaughter facility while another operated a livestock sale barn adjacent to the slaughter facility. The slaughter facility was under FSIS’ supervision while the sale barn was not. Cattle sometimes arrived at the sale barn that were sick/down/dead or would die or go down while at the sale barn. According to personnel at the sale barn, these animals were left for the renderer to collect. The healthy ambulatory animals that remained were marketed to many buyers including the adjacent slaughter facility. When the slaughter facility was ready to accept the ambulatory animals for processing, the cattle would be moved from the sale barn to the slaughter facility where they were subject to FSIS’ inspection.
We requested the slaughter facilities to estimate the number of cattle rejected on a daily basis (there were no records to confirm the estimates). We visited a renderer in the area and found that the renderer had a contract with APHIS to collect samples for BSE testing. In this case, although we could not obtain assurance that all rejected cattle were sampled, the renderer processed a significant number of animals, as compared to the slaughter plants’ estimates of those rejected. Due to the close proximity (less than 5 miles) of the renderer to the slaughter facilities, and the premium it paid for dead cattle that were in good condition, there was a financial incentive for transport drivers to dispose of their dead animals at this renderer.
USDA/OIG-A/50601-10-KC Page 25
In our discussions with APHIS officials in Wisconsin and Iowa, they confirmed that there were plants in their States that also used pre-screening practices. On May 27, 2005, we requested APHIS and FSIS to provide a list of all slaughter facilities that pre-screened cattle for slaughter in locations away from the area designated as the official slaughter facility. Along with this request, we asked for information to demonstrate that either APHIS or FSIS confirmed there was a high likelihood that high-risk animals were sampled at other collection sites.
In response to our request, the APHIS BSE Program Manager stated that APHIS did not have information on slaughter plants that pre-screen or screen their animals for slaughter suitability off their official plant premises. To their knowledge, every company or producer that submits animals for slaughter pre-sorts or screens them for suitability at various locations away from the slaughter facility. For this reason, USDA focused its BSE sample collection efforts at other types of facilities such as renderers, pet food companies, landfills, and dead stock haulers. Further, in a letter to OIG on June 14, 2005, the administrators of APHIS and FSIS noted the following:
"…we believe that no specific actions are necessary or appropriate to obtain reasonable assurance that animals not presented for slaughter are being tested for BSE. There are several reasons for our position. First, we do not believe that the practice is in fact causing us to not test a significant enough number of animals in our enhanced surveillance program to invalidate the overall results. Second, OIG has concluded that because of the geographical proximity and business relationships of the various entities involved in the case investigated, there is reasonable assurance that a majority of the rejected cattle had been sampled. Third, it is also important to remember that the goal of the enhanced surveillance program is to test a sufficient number of animals to allow us to draw conclusions about the level of BSE (if any) in the American herd…We believe that the number we may be not testing because of the "pre-sorting" practice does not rise to a significant level. The number of animals tested to date has far exceeded expectations, so it is reasonable to infer that there are few of the animals in question, or that we are testing them at some other point in the process…APHIS estimated…there were approximately 446,000 high risk cattle…[and APHIS has]…tested over 375,000 animals in less than 1 year. This indicated that we are missing few animals in the high-risk population, including those that might be pre-sorted before entering a slaughter facility’s property."
We obtained 123 APHIS sampling agreements and contracts with firms and plotted their locations within the United States (see exhibit F). We also analyzed the samples tested to the BSE sampling goals allocated to each State under the prior surveillance program. This analysis showed that there are
USDA/OIG-A/50601-10-KC Page 26
39APHIS noted that sites with agreements do not necessarily reflect the entire universe of collection sites and at some sites APHIS collects samples with no payment involved and no agreement in place. OIG agrees that not all collection sites are reflected in our presentation of the 123 sites with reimbursable agreements. OIG believes obtaining sampling agreements is one of the primary methods available to increase sample numbers in areas with sampling gaps.
sampling gaps in two large areas of the United States where APHIS did not have contracts with collection sites. These two areas are shown in the following chart (Montana, South Dakota, North Dakota and Wyoming – Group 1 and Louisiana, Oklahoma, Arkansas, and Tennessee – Group 2): State

APHIS notes that for the current surveillance program, it had established regional goals and APHIS was not trying to meet particular sampling levels in particular States. However, we believe that it would be advantageous for APHIS to monitor collection data and increase outreach when large geographical areas such as the above States do not provide samples in proportion to the numbers and types of cattle in the population.
We also disagree with APHIS/FSIS’ contention that because they have tested over 375,000 of their 446,000 estimate of high risk cattle, few in the high-risk population are being missed, including those that might be pre-screened before entering a slaughter facility’s property. In our prior audit, we reported that APHIS underestimated the high-risk population; we found that this estimate should have been closer to 1 million animals (see Finding 1). We recognize that BSE samples are provided on a voluntary basis; however, APHIS should consider industry practice in any further maintenance surveillance effort. Animals unsuitable for slaughter exhibiting symptoms not inconsistent with BSE should be sampled and their clinical signs recorded. However, this cited industry practice results in rejected animals not being made available to either APHIS or FSIS veterinarians for their observation and identification of clinical signs exhibited ante mortem. Although these animals may be sampled later at other collection sites, the animals are provided post mortem without information as to relevant clinical signs exhibited ante mortem. For these reasons, we believe APHIS needs to
USDA/OIG-A/50601-10-KC Page 27
observe these animals ante mortem when possible to assure the animals from the target population are ultimately sampled and the clinical signs evaluated.

USDA Testing Protocols and Quality Assurance Procedures
In November 2004, USDA announced that its rapid screening test produced an inconclusive BSE test result. A contract laboratory ran its rapid screening test on a brain sample collected for testing and produced three high positive reactive results. As required, the contract laboratory forwarded the inconclusive sample to APHIS’ National Veterinary Services Laboratories (NVSL) for confirmation. NVSL repeated the rapid screening test, which again produced three high positive reactive results. Following established protocol, NVSL ran its confirmatory test, an immunohistochemistry (IHC) test, which was interpreted as negative for BSE.
Faced with conflicting results between the rapid screening and IHC tests, NVSL scientists recommended additional testing to resolve the discrepancy but APHIS headquarters officials concluded that no further testing was necessary since testing protocols were followed and the confirmatory test was negative. In our discussions with APHIS officials, they justified their decision to not do additional testing because the IHC test is internationally recognized as the "gold standard" of testing. Also, they believed that
USDA/OIG-A/50601-10-KC/ Page iv
conducting additional tests would undermine confidence in USDA’s testing protocols.
OIG obtained evidence that indicated additional testing was prudent. We came to this conclusion because the rapid screening tests produced six high positive reactive results, the IHC tests conflicted, and various standard operating procedures were not followed. Also, our review of the relevant scientific literature, other countries’ protocols, and discussions with experts led us to conclude that additional confirmatory testing should be considered in the event of conflicting test results.
To maintain objectivity and independence, we requested that USDA’s Agricultural Research Service (ARS) perform the Office International des Epizooties (OIE) Scrapie-Associated Fibrils (SAF) immunoblot test. The additional testing produced positive results. To confirm, the Secretary of Agriculture requested that an internationally recognized BSE laboratory in Weybridge, England (Weybridge) perform additional testing. Weybridge conducted various tests, including their own IHC tests and three Western blot tests. The tests confirmed that the cow was infected with BSE. The Secretary immediately directed USDA scientists to work with international experts to develop new protocols that include performing dual confirmatory tests in the event of an inconclusive BSE screening test.
We attribute the failure to identify the BSE positive sample to rigid protocols, as well as the lack of adequate quality assurance controls over its testing program. Details of our concerns are discussed in Findings 3 and 4.

Section 2. Testing Protocols and Quality Assurance Controls In November 2004, USDA announced that its rapid screening test, Bio-Rad Enzyme Linked Immunosorbent Assay (ELISA), produced an inconclusive BSE test result as part of its enhanced BSE surveillance program. The ELISA rapid screening test performed at a BSE contract laboratory produced three high positive reactive results.40 As required,41 the contract laboratory forwarded the inconclusive sample to the APHIS National Veterinary Services Laboratories (NVSL) for confirmatory testing. NVSL repeated the ELISA testing and again produced three high positive reactive results.42 In accordance with its established protocol, NVSL ran its confirmatory test, an immunohistochemistry (IHC) test, which was interpreted as negative for BSE. In addition, NVSL performed a histological43 examination of the tissue and did not detect lesions44 consistent with BSE. Faced with conflicting results, NVSL scientists recommended additional testing to resolve the discrepancy but APHIS headquarters officials concluded no further testing was necessary because testing protocols were followed. In our discussions with APHIS officials, they justified their decision not to do additional testing because the IHC is internationally recognized as the “gold standard.” Also, they believed that conducting additional tests would undermine confidence in USDA’s established testing protocols. However, OIG obtained evidence that indicated additional testing was prudent to ensure that USDA’s testing protocols were effective in detecting BSE and that confidence in USDA’s testing procedures was maintained. OIG came to this conclusion because the rapid tests produced six high positive reactive results, confirmatory testing conflicted with the rapid test results, and various standard operating procedures were not followed. Also, our review of scientific literature, other country protocols, as well as discussions with internationally recognized experts led us to conclude that confirmatory testing should not be limited when conflicting test results are obtained. To maintain objectivity and independence in our assessment, we requested the USDA Agricultural Research Service (ARS) perform the Office International des Epizooties (OIE) Scrapie-Associated Fibrils (SAF) 40 ELISA test procedures require two additional (duplicate) tests if the initial test is reactive, before final interpretation. If either of the duplicate tests is reactive, the test is deemed inconclusive. 41 Protocol for BSE Contract Laboratories to Receive and Test Bovine Brain Samples and Report Results for BSE Surveillance Standard Operating Procedure (SOP), dated October 26, 2004. 42 The NVSL conducted an ELISA test on the original material tested at the contract laboratory and on two new cuts from the sample tissue. 43 A visual examination of brain tissue by a microscope. 44 A localized pathological change in a bodily organ or tissue.
immunoblot.45 ARS performed the test at the National Animal Disease Center because NVSL did not have the necessary equipment46 (ultracentrifuge) to do the test. APHIS scientists observed and participated, as appropriate, in this effort. The additional tests conducted by ARS produced positive results. To confirm this finding, the Secretary requested the internationally recognized BSE reference laboratory in Weybridge, England, (Weybridge) to perform additional confirmatory testing. Weybridge conducted various tests, including their own IHC methods, as well as three Western blot methods. The tests confirmed that the suspect cow was infected with BSE. Also, Weybridge confirmed this case as an unequivocal positive case of BSE on the basis of IHC. As a result of this finding, the Secretary immediately directed USDA scientists to work with international experts to develop a new protocol that includes performing dual confirmatory tests in the event of another inconclusive BSE screening test. Finding 3 Rigid Protocols Reduced the Likelihood BSE Could be Detected APHIS relied on a single test method, as well as a histological examination of tissue for lesions consistent with BSE, to confirm the presence of BSE even though discrepant test results indicated further testing may be prudent. When IHC test results were interpreted as negative, APHIS concluded the sample tested negative for BSE. Subsequent independent tests initiated by OIG using a different testing method, as well as confirmatory testing by Weybridge, determined that the suspect sample was a positive case of BSE. APHIS Declares BSE Sample Negative Despite Conflicting Results When the tissue sample originally arrived at NVSL in November 2004 from the contract lab, NVSL scientists repeated the ELISA screening test and again produced three high positive reactive results. NVSL scientists cut out two sections of the brain sample for IHC testing. One section was used for an experimental procedure that was not part of the confirmatory testing protocol, and the other cut was for normal IHC testing using scrapie for a positive control.47 According to NVSL scientists, the experimental test results were inconclusive but the IHC test was interpreted as negative. The NVSL scientists were concerned with the inconsistencies and conducted 45 The OIE SAF immunoblot is an internationally recognized confirmatory test, often referred to as a Western blot test. There are different types of Western blots; the OIE SAF immunoblot includes enrichment steps taken with the sample prior to the standard Western blot steps. 46 APHIS has now ordered the necessary equipment for NVSL.

47 A positive control is a sample that is known to contain a given disease or react in the test. The sample then can be used to make sure that the test for that disease works properly. In the case of BSE, tissue infected with either scrapie or BSE can serve as a positive control for an IHC test for BSE since both are different forms of the same disease (transmissible spongiform encephalopathy or TSE).
another IHC test using BSE as a positive control.48 The test result was also interpreted as negative. Also, according to the NVSL scientists, the histological examination of the tissue did not detect lesions consistent with BSE. After the second negative IHC test, NVSL scientists supported doing additional testing. They prepared a plan for additional tests; if those tests had been conducted, BSE may have been detected in the sample. The additional tests recommended by NVSL scientists, but not approved by APHIS Headquarters officials, were the IHC using other antibodies (IHC testing using different antibodies ultimately produced positive results); IHC testing of additional regions of the brain (the cerebellum tested positive); regular and enriched (OIE-like) Western blots (the obex and cerebellum tested positive); and variable rapid tests (the obex and cerebellum tested positive with two different rapid tests). NVSL officials also recommended that the sample be sent to Weybridge for confirmatory testing (to conduct IHC and OIE Western blot tests). In June 2005, Weybridge conducted IHC testing with three different antibodies, including the antibody used in the United States (tested positive), the OIE Western blot (tested positive), a modified commercial kit Western blot (negative) and the NaPTA49 Western blot (tested positive). We obtained information as to the differing protocols used by other countries. We found that while APHIS determined that additional testing was unnecessary after the IHC test, other countries have used multiple tests to confirm positives. In Japan, for example, all reactive screening test samples are examined by both IHC and a Western blot (different from the OIE SAF immunoblot). In the United Kingdom (U.K.), IHC and Western blot (different from the OIE SAF immunoblot) tests are used for all animals that test positive with a screening test. When IHC and the Western blot fail to confirm a positive rapid test, the U.K. resorts to a third test, the OIE SAF immunoblot. With these procedures in place, both Japan and the U.K. have found BSE cases that were rapid test reactive, IHC negative, and finally confirmed positive with a Western blot. Evidence Indicated Additional Testing Would Be Prudent We also spoke with an internationally recognized BSE expert regarding the advisability of limiting confirmatory testing when conflicting results are obtained. This official expressed concern about limiting confirmatory tests to the IHC despite its status as one of the “gold standard” tests. He advised that the IHC is not one test; it is a test method that can vary significantly in sensitivity from laboratory to laboratory. New antibodies can improve or

48 The NVSL uses scrapie as the positive control as part of its normal IHC testing procedures. Due to the conflicting results between the ELISA and IHC tests, the NVSL conducted another IHC test with BSE as the positive control. Subsequently, the NVSL modified the Confirming Inconclusive Results from BSE Testing Laboratories at the NVSL SOP to show that all IHC tested BSE inconclusive samples from contract laboratories will use BSE as the positive control. 49 Sodium phosphotungstic acid.

reduce sensitivity, as can variations in many of the reagents50 used. He explained that his laboratory had experienced cases where an initial confirmatory IHC test was challenged by either a more extensive IHC test or “…applying a more sensitive immunoblot.” He emphasized the importance of having additional confirmatory testing to resolve discrepant results since there are many variables, and most of the variability appears to be due to test performance of the laboratory. OIG became concerned that APHIS relied on its confirmatory test methods when rapid screening tests produced high positive reactive results six times.51 Also, we found that APHIS did not pursue and/or investigate why the ELISA produced high reactive positives. An official from the manufacturer of the ELISA test kit told us that they requested, but did not receive, information on the inconclusive reported by USDA in November 2004. These officials requested this information in order to understand the reasons for the discrepant results. The Bio-Rad ELISA rapid screening test is internationally recognized as a highly reliable test and is the rapid screening test used for USDA’s surveillance effort. According to APHIS officials, they felt it would be inappropriate to collaborate on the one sample because Bio-Rad is a USDA-APHIS regulated biologics company and only one of several competing manufacturers. To maintain confidence in USDA’s test protocols, it would have been a prudent course of action for USDA to determine why such significant differing results were obtained. The fact that they did not pursue this matter caused concerns relating to testing quality assurance procedures. In this regard, we found lack of compliance with SOPs relating to laboratory proficiency and quality assurance (see Finding 4), and, in this case, the storage of sampled material and reporting of test results. We found that the NVSL did not prepare a report to document its confirmatory testing of the November 2004 sample. The SOP52 states that the BSE network laboratory initiating the inconclusive will receive a report of the case. NVSL officials could not explain why a final report had not been prepared. We also found that the inconclusive sample was frozen prior to IHC confirmatory testing. APHIS protocols state that samples are not to be frozen prior to laboratory submission. The OIE Manual of Diagnostic Tests and Vaccines for Terrestrial Animals states that the tissues for histological or IHC examination are not to be frozen as this will provide artefactual53 lesions that may compromise the identification of vacuolation,54 and/or target site location. Although the sample was frozen, APHIS did not conduct a Western 50 A substance used in a chemical reaction to detect, measure, examine, or produce other substances. 51 The six high positive reactive results were from three tests of the submitted sample (multiple runs of the same test). 52 Confirming Inconclusive Results from Bovine Spongiform Encephalopathy Testing Laboratories at the NVSL SOP, dated August 13, 2004. 53 A structure or feature not normally present but visible as a result of an external agent or action, such as one seen in a microscopic specimen after fixation. 54 A small space or cavity in a tissue.

blot test on the sample. An NVSL official said freezing the sample does not make it unsuitable for IHC. APHIS determined that the sample was suitable for IHC and therefore, in accordance with its SOP, did not conduct a Western blot test. APHIS also handled the December 2003 BSE positive differently than the November 2004 sample. For the December 2003 BSE positive sample, APHIS conducted several confirmatory tests in addition to the IHC testing and histological examination (unlike the November 2004 sample tests, both of these were interpreted as positive). ARS performed two Western blots (Prionics Check Western blot and an ARS developed Western blot). When we questioned why the samples were handled differently, APHIS officials stated that the Western blots were done because the IHC in December 2003 was positive. The additional testing was done to further characterize the case, because it was the first U.S. case; the additional testing was not done to decide whether the case was positive or negative. We discussed our concerns with limiting confirmatory testing, particularly given conflicting results, with the APHIS Administrator and staff in May 2005. He explained that international standards recognized more than one “gold standard” test. In setting up its testing protocols, USDA had chosen one as the confirming test, the IHC test, and stayed with it. APHIS protocols only allow a Western blot in cases where the sample has become unsuitable for IHC tests (e.g., in cases where the brainstem architecture is not evident). International standards, he continued, accept a tissue sample as negative for BSE if its IHC test is negative. Once the test is run in accordance with protocols, additional tests undermine the USDA testing protocol and the surveillance program. He concluded that since APHIS’ protocols accepted the IHC test as confirming the presence or absence of BSE, no further testing was necessary. According to protocol, the tissue sample was determined to have tested negative for BSE. On June 24, 2005, USDA announced that the additional testing by the BSE reference laboratory in England confirmed the presence of BSE in the tissue sample. To obviate the possibility that a future sample would be declared negative and then found positive, the Secretary of Agriculture announced a change to APHIS’ testing protocols that same day. He called for “dual confirmatory tests in the event of another ‘inconclusive’ [reactive] BSE screening test.” He also indicated that he would reinforce proper procedures so that samples will not be frozen, and to spot-check the laboratories to see that they complete reports as required. APHIS issued a SOP on the new confirmatory testing protocols on November 30, 2005.

For the period of time from January 1, 2005, until October 15, 2005, there were 23 instances of discrepancies in results from 35 flocks. Of those 23 instances, 14 were caused by laboratory error (paperwork or sample mix-up), 3 results from field error, 5 were not completely resolved, and 1 originated from the use of a non-approved laboratory for the first test. As a result of inconsistencies, one laboratory’s certification was revoked by APHIS-VS.

Monthly Test Results APHIS reports ongoing surveillance totals monthly. The BSE ongoing surveillance program will sample approximately 40,000 animals each year. Under the program, USDA will continue to collect samples from a variety of sites and from the cattle populations where the disease is most likely to be detected, similar to the enhanced surveillance program procedures.
