Prions are also one of the most difficult of infectious agents to destroy.

I first discovered "laughing sickness", also called "kuru", in the early 1980's upon memorizing the Guiness Book Of World Records. It was listed as the most fatal known disease. It is a prion disease which is spread by eating human brains and flesh, creepy.

Maybe feeding cattle to cattle was not such a good idea.
