Which statement is true about the Veterinary Feed Directive drugs by October 2015?

• A. Avilamycin, Florfenicol, Tilmicosin were approved VFD drugs
• B. Penicillin was a VFD drug
• C. No drugs were approved as VFD drugs
• D. All antibiotics were available OTC as VFD drugs

Answer: (A)

The key idea is that the Veterinary Feed Directive (VFD) controls how certain antibiotics can be used in animal feeds, requiring oversight from a licensed veterinarian and adherence to labeled directions. By October 2015, the FDA had designated specific medicated feeds as VFD drugs, meaning they could be used in feed only under a valid VFD issued by a veterinarian. Avilamycin, florfenicol, and tilmicosin were among the drugs that had VFD status by that time, reflecting the shift toward veterinary supervision rather than over-the-counter use. The other statements conflict with the VFD framework: it does not allow all antibiotics to be used OTC, and it does not imply that no drugs were approved as VFD drugs.
