I found this very interesting article on mad cow:

I think he’s on the right track. If so, there are certain conditions that must be met before mad cow can occur.

I always thought it was suspicious how many cows they found with the disease, yet we didn’t see very many (relatively) in humans.

The bad news means that if he’s right, they know exactly how to cause mad cow and can easily do it.
