I expect to see something about the blood supply in
the next few weeks in my digests -- will pass it on
when I do.

In 1997 the US govt. banned cattle feeds containing
CNS tissue (protein and bone meal) of cattle, sheep, &
goats, but blood meal is still allowed.  This article
has several links; they've quarantined this cow's two
most recent calves, but still haven't found where she
was infected originally.

http://www.msnbc.msn.com/id/3797510/
"...�The reason for concern with these calves is that
even though it is an unlikely means of spreading the
disease, there is the potential that the infected cow
could pass the disease onto its calves,� he said...
...DeHaven said the emphasis of the widening
investigation is on finding the birth herd of the
slaughtered cow, since it likely was infected several
years ago from eating contaminated feed...The
incubation period in cattle is four to five years,
said Dr. Stephen Sundlof of the Food and Drug
Administration...

"...�Here�s the problem. The feed ban has been grossly
violated by feed mills,� Stauber said in a telephone
interview from his home in Madison, Wis.  In one such
case, X-Cel Feeds Inc. of Tacoma, Wash., admitted in a
consent decree in July that it violated FDA
regulations designed to prevent the possible spread of
the disease.  The Food and Drug Administration says
only two companies have serious violations of the 1997
regulations..."

One of the inserts states: "TSEs [Transmissible
Spongiform Encephalopathies] are familial or
inherited, which means they are passed on genetically
from parents to offspring."  That would mean that her
calves (and any former calves she had) _could_ be
infected.  

Other TSE's include 'kuru' which was passed on by
human cannibalism (and I think it's basically extinct
'in the wild' now), Creutzfeldt-Jakob disease (unknown
how humans aquire it, although there is a genetic
component: "There is a genetic susceptibility to TSEs.
For example, CJD occurs sporadically, or randomly, in
about one in 1 million people. There is a gene
mutation that runs in families and causes 5 percent to
10 percent of cases of CJD."), and 'scrapie' in sheep
- not sure if that was only from eating sick sheep
tissue, or congenitally passed.

Controversy:
http://www.msnbc.msn.com/id/3801706/
"...Cattle are believed to have become infected with
BSE when they were fed the rendered remains of sheep,
which have their own TSE called scrapie.  Rendering or
processing food can destroy the prions, but only with
difficulty. Just cooking will not do the trick."  Yet
earlier it was written that 'pets cannot become
infected by eating the rendered animal's contaminated
tissue because rendering destroys the prions.' (Cats
can get TSEs, dogs seem to be immune thus far.)

More controversy:
"A recent Swiss study suggested that, in theory,
muscle tissue � which would include steaks � could
carry the agent."

Here in Colorado and a few contiguous states there's
been a problem with Chronic Wasting Disease, a TSE, in
deer and elk; it was recently discovered in Wisconsin
as well.  Locally, hunters who kill deer or elk that
appear to be ill are requested to submit the head for
testing to state authorities; I think concerned
hunters can have any hunted animal tested, for a
nominal fee.

I expect to have more reliable info next week, and
will post it.
