To find out why (from someone other than yours truly), click here to read an op-ed piece from yesterday’s New York Times, written by Donald Kennedy, a former commissioner of the United States Food and Drug Administration.
Here is one essential part of Kennedy’s essay:
"More than 30 years ago, when I was commissioner of the United States Food and Drug Administration, we proposed eliminating the use of penicillin and two other antibiotics to promote growth in animals raised for food. When agribusiness interests persuaded Congress not to approve that regulation, we saw firsthand how strong politics can trump wise policy and good science. Even back then, this nontherapeutic use of antibiotics was being linked to the evolution of antibiotic resistance in bacteria that infect humans."
