I don't know much beyond the article in terms of testing and blood.

I just know that any amount seems to be hazardous and no amount of cooking, baking, microwaving etc. destroys them.

As far as I know, there's no way of destroying the buggers in meat or anything else.

And, they are in rat urine left on leaves, twigs, rocks, ?water?, in the forest etc.

Rohwer points out, however, that even blood from heavily infected people contains only 5,000 infective doses' worth of prions, so filtering of donated blood should bring the amount well below the amount required to cause disease.

The above is the part that raised questions in my mind. I didn't know they'd established a 'safe limit' for these things.

One more reason to hate rats...
