BSE CASE CONFIRMED IN ALBERTA OTTAWA, August 15, 2008 -
The Canadian Food Inspection Agency (CFIA) has confirmed bovine spongiform encephalopathy (BSE) in a six-year-old beef cow from Alberta. No part of the animal’s carcass entered the human food or animal feed systems.
The animal’s birth farm has been identified, and an investigation is underway. The CFIA is tracing the animal's herdmates at the time of birth and examining possible sources of infection. The age and location of the infected animal are consistent with previous cases detected in Canada.
This case was detected through the national BSE surveillance program, which has been highly successful in demonstrating the low level of BSE in Canada. The program continues to play an important role in Canada’s strategy to manage BSE.
Canada remains a Controlled Risk country for BSE, as recognized by the World Organisation for Animal Health (OIE). Accordingly, this case should not affect exports of Canadian cattle or beef.

Amazing what you will find when you look. The Canadians are doing a far better job than the US in confirming BSE/TSE cases. ...TSS

Review on the epidemiology and dynamics of BSE epidemics
Cases of atypical BSE have only been found in countries having implemented large active surveillance programs. As of 1st September 2007, 36 cases (16 H, 20 L) have been described all over the world in cattle: Belgium (1 L) , Canada (1 H)15, Denmark (1 L)16, France (8 H, 6 L)17, Germany (1 H, 1 L) , Italy (3 L)18, Japan (1 L) , Netherlands (1 H, 2 L)19, Poland (1 H, 6 L)20, Sweden (1 H)21, United Kingdom (1 H)22, and USA (2 H)23. Another H-type case has been found in a 19 year old miniature zebu in a zoological park in Switzerland . It is noteworthy that atypical cases have been found in countries that did not experience classical BSE so far, like Sweden, or in which only few cases of classical BSE have been found, like Canada or the USA.
And last but not least, similarities of PrPres between Htype BSE and human prion diseases like CJD or GSS have been put forward , as well as between L-type BSE and CJD . These findings raise questions about the origin and inter species transmission of these prion diseases that were discovered through the BSE active surveillance.

USA BSE ACTIVE SURVEILLANCE ???
Please remember, the last two mad cows documented in the USA i.e. Alabama and Texas, both were of the 'atypical' BSE strain, and immediately after that, the USDA shut down the testing from 470,000 to 40,000 in the U.S. in 2007 out of about 35 million cattle slaughtered. also, science is showing that some of these atypical cases are more virulent to humans than the typical UK BSE strain ;
***Atypical forms of BSE have emerged which, although rare, appear to be more virulent than the classical BSE that causes vCJD.***

In this context, a word is in order about the US testing program. After the discovery of the first (imported) cow in 2003, the magnitude of testing was much increased, reaching a level of >400,000 tests in 2005 (Figure 4). Neither of the 2 more recently indigenously infected older animals with nonspecific clinical features would have been detected without such testing, and neither would have been identified as atypical without confirmatory Western blots. Despite these facts, surveillance has now been decimated to 40,000 annual tests (USDA news release no. 0255.06, July 20, 2006) and invites the accusation that the United States will never know the true status of its involvement with BSE.
In short, a great deal of further work will need to be done before the phenotypic features and prevalence of atypical BSE are understood. More than a single strain may have been present from the beginning of the epidemic, but this possibility has been overlooked by virtue of the absence of widespread Western blot confirmatory testing of positive screening test results; or these new phenotypes may be found, at least in part, to result from infections at an older age by a typical BSE agent, rather than neonatal infections with new "strains" of BSE. Neither alternative has yet been investigated.
