The Animal Drug Availability Act of 1996 requires certain medicated feed mills to be licensed with FDA, and the agency recently published a list of licensed facilities and Veterinary Feed Directive (VFD) distributors.  

According to the FDA, the seller of a new animal drug intended for use in the manufacture of medicated animal feed must have a written statement from the buyer that the buyer has an approved feed mill license and possesses current approved Type B and/or Type C feed labeling for the drug, unless FDA has exempted the seller

The agency’s initiative for judicious use of medically important antimicrobials in medicated feed or drinking water of food-producing animals establishes a framework for phasing out production uses of antimicrobials important in treating humans, and phasing in veterinary oversight of the remaining therapeutic uses of such drugs. This proposal sets a three-year timeframe implementing veterinary oversight of antimicrobials in feed and water and streamlining of the VFD), which provides the framework through which veterinarians oversee the use of drugs added to feed for therapeutic purposes. Under the Draft Guidance, a range of drugs currently available over the counter would fall under the VFD.

The FDA website now contains updated lists of approved medicated feed mill licenses sorted by name or by state, and lists of VFD distributors sorted by company name or by state.
