Antibiotic resistance was a major topic last December. The Food and Drug Administration (FDA) calls it a challenging problem. It implemented major changes by requiring drug veterinary oversight and re-labeling of some antimicrobials.
Dr. David White with the FDA says despite efforts to curb drug use, more work is needed.
All 26 affected animal health companies are voluntarily complying with new rules and 31 out of 283 drug products have already been withdrawn completely from the market. The changes are intended to happen over a three year period.
White says the FDA will release progress reports every six months.
