This document discusses new FDA regulations regarding the use of medically important antimicrobials in animal agriculture. Specifically, it will require veterinary oversight for these drugs and remove approvals for their use solely for production purposes like growth promotion. Key elements include: drugs affected are those considered important for human medicine and administered via feed or water. A veterinary feed directive (VFD) provides the framework for veterinary oversight of feed use drugs. The VFD regulations specify information required on the directive and responsibilities of veterinarians, distributors, and producers. The changes aim to curb antimicrobial resistance while still allowing therapeutic uses under veterinary guidance.

31. VFD Final Rule: Drug CategoriesVFD Final Rule: Drug Categories
Feed-use drugs are assigned to one of two categories:
Category I - drugs having the lowest potential for
residues
Category II - drugs having the highest potential for
residues
Category determines whether a facility needs to be licensed to handle
the drug in the Type A form
Definition of Category II has been revised to eliminate the automatic
classification of VFD drugs into Category II
This change applies to the existing approved VFD drug products, in
addition to the products that will become VFD under GFI #213

Returning to the table of medically important antibiotics administered to food animal in medicated feed.
Some applications are expected to be withdrawn and some are expected to transition to VFD marketing status.
For example, Penicillin and Oleandomycin are underlined because they currently only have production uses, so barring addition of a therapeutic use between now and December of 2016, we would not expect to see either of them legally used in feed beginning 1 January 2017.
The italicized drugs, neomycin, lincomycin, tylosin, virginiamycin, chlorotetracycline and oxytetracycline, currently have both applications with production uses and applications with therapeutic uses. By December of 2016, the production uses are expected to be withdrawn leaving only the therapeutic uses. These therapeutic uses will then have a VFD marketing status. Once these applications have VFD marketing status they will fall under the authority of the 2015 VFD rule.
