Which of the following is one FDA policy that has helped combat antibiotic resistance?

• A. Increased veterinary oversight of antimicrobials (VFDs)
• B. Phasing out production uses of medically important antimicrobials
• C. Expanded use of antimicrobials for growth promotion
• D. Keeping antibiotics available OTC for animals

Answer: (A)

Requiring veterinary oversight through the Veterinary Feed Directive strengthens antibiotic stewardship by ensuring that antimicrobial drugs used in animal feeds are prescribed and supervised by a licensed veterinarian. The veterinarian assesses the animal’s health, selects an appropriate drug, dose, and duration, and enforces withdrawal times, with proper recordkeeping. This professional oversight reduces unnecessary or inappropriate use, limits off-label use, and decreases overall bacterial exposure to antibiotics, which slows the development and spread of resistance.

Phasing out production uses of medically important antimicrobials is beneficial, but the most direct daily practice that reduces resistance is having a veterinarian guide and approve use through the directive. Keeping antibiotics available over the counter would increase misuse, and expanding their use for growth promotion would raise selection pressure for resistant bacteria.
