Also prions can stick around in the pig's meat. You can't destroy a prion except by enzymatic action(not likely) or by incinerating it. The latter is seriously suboptimal for the enjoyment of the meat.

Chronic wasting disease in deer is a prion disease that deer and sheep can get. As far as we know humans can't. Of all the mad cow meat consumed in the UK, only one person who had brain got it.

Creutzfeldt–Jakob disease is a human prion disease spread by eating human brains.
