If the human form for BSE can be spread between humans by blood transfusions as stated in the UK conference as posted by second reader, doesn't that then make blood a high risk material and throw all of our saftey thoughts out the window? The fact that Cal. tech is going to have an inexpensive blood test for BSE ready within six months also seems to point to the fact that blood carries the prions and is a high risk material. It doesn't make sense to me that nobody has responded to these posts by second reader because they seem to be big news.
