As the whole world knows by now, they've found a case of mad cow disease in the USA. Reported, but under-stated, is the fact that the meat processers tested the animal that arrived half-parylized, but had no hesitation in sending it right into the slaugherhouse and into our food supply. And indeed the law requires nothing else.
I spent several years living in a country — England — which woke up gradually to the fact that it had a serioius Mad Cow disease problem. [Best newspaper cartoon. One cow says to the other, “So, what do you think about this Mad Cow disease?” Second cow replies, “Doesn't bother us ducks.”] When I got back to the US I found tha the Red Cross wouldn't take my blood in blood drives, because I'd lived (oddly the rule didn't apply to mere tourists) in a country where there were reported cases of Mad Cow disease. I presume that this rule will now be relaxed for domestic blood donations at least?
If we continue the path of recapitulating the not-very-admirable British experience (denial that there's a big problem, no change in regulations, followed by a growth in the problem), expect a bunch of jokes about which of our politicians are infected. Probably Karl Rove is working them up already….
