There is no doubt that CJS can attack humans; it has done so in lots of contexts. There's no question it can be transmitted by eating contaminated flesh. The first cases were discovered in the rather macabre context of New Zealand cannibals--obviously that wasn't called mad cow disease; the NZ cannibals called it "kudu." But Kudu is the same thing as scrapie (in sheep and goats), BSE, and CJS. It's the same agent, which is called a "prion" and it is apparently both invariably fatal and communicated in nearly 100% of the cases where the contaminated flesh is ingested. It acn also be spreak by much more tenuous mechanisms. In one case, a woman got it because her surgeon had used instruments he had also used on a man who had died of something else but whose autoposy revealved him to have CJS, if I remember the case correctly. Oh yes, he'd subjected the instrumenmted to the normal cleaning and desterilization techniques. It's jsut taht they're no good against prions, which are practically indestructible. There is no immune defense to CJS. Personally, I think concern is entirely in order. --jks --- from list marxism-thaxis-AT-lists.village.virginia.edu ---
