With 100 human cases of vCJD(human BSE) and 200,000 cases of BSE in cattle in
England it is extremely unlikely that we will see the index case of BSE of US
origin in humans. Your comment about the risk of being killed in a car crash is
more likely that being killed by BSE in England even if for a cow. That is how
much BSE is blown out of proportion.

The fact that we feed a great deal less animal protein to cattle in the US than
they do in the EU makes the spread of BSE much less likely in the US. We have
cheap oil seed meals that aren't available in the EU and the meat, blood and
bone meal it fed to hogs, chickens and fish where it has more value. Of course
now there is no ruminate protein being fed to ruminates at all.
