I just read this in a letter to the editor today:
The infectious agents in mad cow disease, prion proteins, are
naturally occurring. They become lethal only when their structure =
is
altered and they somehow induce the alteration of other prion
proteins, leading to the gradual deterioration of brain tissue as
seen in Creutzfeldt-Jakob disease in humans.
http://nytimes.com/2004/01/01/opinion/L01COWW.html
It would seem then prions are normally occurring proteins, not a=20
specific invisible agent that lurks so frighteningly. Though they=20
remain a "mystery protein" and all diseases of the prion are fatal,=20
prions probably do things other than just disease.=20

I wouldn't bank on that, I'm not sure that they couldn't get into your
system by breathing them. But then, I don't think I'll be volunteering
to test that. (some people would say I have enough problems)

Don't eat the bone ash. You can only get the prions in your system by
eating=20
them.
