Try the "less emotional" story on the press and see if they bite. This is a true comedy of errors for the USDA.
Clarence, the cow tested positive using the IHC, WB, SAF, and Histopathology, in England. There is no doubt as to the infectivity. All other countries in Europe plus Japan and Canada use the WB plus IHC for confirmatory tests after a rapid is positive. EITHER/OR can be positive and is confirmed.
"Intensive measures"? Concentrating samples is common practice in Western Blot technology, that's why it can find prions in subclinical cases (younger animals).
Testing has become a "Food Safety Issue" here as it has been in Europe, like it or not. Even though the USDA disagrees.
