John, << I find it difficult to believe that people would be allergic to beef. I CAN believe that people are allergic to the unnatural foods that are fed TO the beef, and are having a reaction to that which is transmitted along with it. >> If the natives of New Guinea that practiced cannibalism several hundred years ago before the advent of pesticides etc. succumbed to the human variant of mad cow disease, why should allergies to beef be ruled out? << I don't know too much about allergies. >> That sums it up for you.
