Veterinary Feed Directive Distributor Notifications - Updated June 2017

Title 21 of the Code of Federal Regulations (CFR) Part 515 (21 CFR 515) requires certain medicated feed mills to be licensed with FDA. Licensed facilities are allowed to manufacture animal feeds from Category II, Type A medicated articles. Category II drugs require a withdrawal period at the lowest use level for at least one major species for which they are approved, or are regulated on a “no-residue” basis or with a zero tolerance because of a carcinogenic concern regardless of whether a withdrawal period is required in any species. (See 21 CFR 558.3 for definitions of Category II and Type A medicated articles).  In addition, FDA may exempt facilities that manufacture certain types of medicated feed from the requirement of obtaining a medicated feed mill license.
