Seeing the Forest (try searching on "seetheforest" or can someone who knows how to do these things make the link?) reports that vCJ may already be causing deaths in the US, with undiagnosed wasting diseases, misdiagnosed Alheimer's disease, and misdiagnosed MS.
NO animals that are fed feed are safe, for example, although chickens do not come down with Mad Cow, they are sometimes fed contaminated feed and may be carriers.
Unsafe animals include pork and lamb and, well, pretty much everything.
This is worse news than I expected.
