BSE in USA
Tags: TSE, USA
Source: FDA
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'?
SNIP...
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.
