Antibiotic-resistant bacteria, and avian flu, are being promoted largely through the excess use of antibiotics in factory farms in the U. S. and elsewhere.

Nonsense! Avian flu has absolutely nothing to do with antibiotic use (or abuse). I was in agreement with you until you said that.

Agreed. I should have said something like, "antibiotic-resistant bacteria and avian flu are being promoted largely through the excess use of antibiotics in factory farms on the one hand, and by factory-farmed birds generally on the other." Flu is a virus, not a bacterium.
