FDA Requires VFD Beginning Jan. 1


Beginning January 1, livestock producers will have new federal rules to follow when feeding their animals. The Food and Drug Administration will require a Veterinary Feed Directive (VFD) for all medically important antibiotics administered in feed and a veterinary prescription for all medically important antibiotics used in water. A VFD is a written statement issued by a licensed veterinarian that authorizes use of a VFD drug in or on animal feed.

A list of the animal drugs MKC currently sells which fall under VFD regulations are listed below. To use any of these drugs regulated by FDA, a VFD from a veterinarian is required to be submitted to the retailer (MKC) before the feed can be purchased. The VFD must be in writing. By regulation, phone calls from a veterinarian will not suffice.

The VFD will indicate the vet name, client, name of drug, reason for feeding, feeding rate, the number of animals, expiration date, and other pertinent information. MKC is then required to monitor the amount of feed you purchase and keep the VFD for two years.

If you mix your feed and want to purchase the undiluted form of these drugs, you must have a VFD on hand before you feed it but not to purchase it. The retailer (MKC) will require you to sign an acknowledgment letter verifying you will have a VFD before you feed the product.
