BSE in USA
Tags: TSE, USA
A final investigation summary into the Californian case of BSE in April this year has been published by FDA.
The report concludes that "compliance with BSE feed regulations was excellent" and that "none of the facilities had used prohibited material in their feed manufacturing during the entire period of interest". The cow, obviously, was not infected through feed, but developed the disease from a 'spontaneous mutation'.
As this is certainly good news regarding the effectiveness of the feed ban system in the US, the fact that this cow had atypical BSE makes it more likely, not less, that there are more cases like this one in the US dairy herd. If a spontaneous mutation can develop once, it can develop several times. The relevance of atypical BSE for public health is unclear at this time, but there are indications that L-type atypical BSE, as diagnosed in the Californian cow, is transmissible to primates. The question then is how reliably such cases can be detected by the US surveillance system. The April case was detected in the course of "random testing".

Are USDA assurances on mad cow case 'gross oversimplification'?
What irks many scientists is the USDA’s April 25 statement that the rare disease is “not generally associated with an animal consuming infected feed.”
The USDA’s conclusion is a “gross oversimplification,” said Dr. Paul Brown, one of the world’s experts on this type of disease who retired recently from the National Institutes of Health.
"(The agency) has no foundation on which to base that statement.”
“We can’t say it’s not feed related,” agreed Dr. Linda Detwiler, an official with the USDA during the Clinton Administration now at Mississippi State.
In the May 1 email to me, USDA’s Cole backed off a bit. “No one knows the origins of atypical cases of BSE,” she said
The argument about feed is critical because if feed is the cause, not a spontaneous mutation, the California cow could be part of a larger outbreak.
