We in Britain sometimes forget that at least some parts of the world aren't
infested with BSE, and your comments here are all accurate as far as the
current thesis on how BSE appeared (and is now spreading across Europe,
apparently).
I'm sure someone on the list a while ago tried to use prions as part of some
complex argument that I certainly didn't understand (something about
replication, and how prions do it). Prions are unusual proteins, but that's
about as much as I know... oh, apart from that they're virtually
indestructible (heat, cold, poison etc. nothing works on them).
The Oprah case is interesting for other reasons. This was mentioned again
recently somewhere, I forget where, and I was quite amused by the... what's
it called... food disparagement law she was accused of breaking. I mean I
understand what it represents- potential loss of revenue for producers
because someone prominent says it's crap- but it's just the name of the law
that's amusing (to my mind, anyway).
Richard's our resident Oprah expert, maybe he recalls this incident better
than I.
