Livestock producers and veterinarians dedicate their lives and livelihood to the provision of high quality, safe and nutritious food for millions of Americans. Producers have a real passion and pride for their industry, from progressive ranch management and environmental sustainability, to on farm animal welfare and preventative health practices. Veterinarians have the indispensable role as stewards of animal health, animal welfare and public health. With the producer’s knowledge and experience and the veterinarian’s scientific training and clinical expertise, we are working together across the State of California to reduce the rate of antimicrobial resistance.
The following resources are designed to aid the veterinarian and producer in the development and application of herd health plan and responsible antimicrobial use practices.
In California, a VCPR is established when the client has authorized the licensed veterinarian to assume responsibility for making medical judgements and the need for medical treatment of the patient (including the prescription of antimicrobials) AND the veterinarian has agreed to assuming that responsibility and has communicated with the client an appropriate course of treatment.
For a valid VCPR, the veterinarian must be personally acquainted with the care of the animal(s) by way of an examination of the animal or by medically appropriate and timely visits to the premises where the animals are kept AND have enough knowledge of the animal(s) to give at least a general or preliminary diagnosis of the medical condition.VCPR (16 CCR § 2032.1) California’s definition of a VCPR has been accepted by the FDA to fulfill the national requirements. VCPR Practice Model – Youth Agriculture CDFA Informational Brochure VCPR Example – Agent Authorization This document is not required for youth agriculture participation, or to establish or maintain a VCPR. The intent of the document is to inspire creative solutions within the context of the definition of a VCPR in California. A VCPR is validated by the communications and actions between the veterinarian and the client.

Effective January 1, 2018, a licensed veterinarian who renews his or her license shall complete a minimum of one credit hour of continuing education on the judicious use of medically important antimicrobial drugs every four years as part of his or her continuing education requirements.
An explanation of when the first unit of CE is required can be found at the Veterinary Medical Board’s website.California VMB Approved CE Providers The California VMB requests that any provider that is not a statutorily recognized entity seek approval through the American Association of Veterinary State Boards (AAVSB) Registry of Approved CE (RACE). Module 23: Use of Antibiotics in Animals is a training module for the National Veterinary Accreditation Program within USDA APHIS. The completion of this module counts as one credit hour of CE on the judicious use of MIADs.
According to the Livestock: Use of Antimicrobial Drugs law (FAC § 14400 – 14408), a medically important antimicrobial drug (MIAD) can be used to treat, control the spread of, and, in some cases, prevent disease or infection in livestock under the professional oversight of a veterinarian. Veterinarians may authorize use of MIADs when necessary for the following:
- To treat a disease or infection.
- To control the spread of a disease or infection.
- In relation to surgery or a medical procedure.
Any use of MIADs for promoting weight gain or improving feed efficiency is prohibited by law. The law also prohibits any use of MIADs in a “regular pattern” unless the use is necessary for one of the three purposes described above (treatment, control of a disease outbreak, or for surgeries or medical procedures). Outside of “regular pattern” use, MIADs may also be used when, in the professional judgment of a licensed veterinarian, it is needed for prophylaxis to address an elevated risk of contraction of a particular disease or infection.Judicious Use of Antimicrobials FDA Communications and Documents Judicious Therapeutic Use of Antimicrobials AVMA position statement Key Elements for Implementing Antimicrobial Stewardship Plans in Bovine Veterinary Practices Working with Beef and Dairy Operations AABP guidelines
Extralabel use refers to the use of an FDA approved drug in a manner that is not in accordance with the approved label directions.
Under the provisions of AMDUCA and its implementing regulations, the FDA recognizes the professional judgment of veterinarians, and permits the extralabel use of drugs by veterinarians with a valid VCPR under certain conditions following recordkeeping and labeling requirements. In food-producing animals, extralabel uses of antimicrobials must not be administered via feed (with an exception made for minor use/minor species), nor result in a residue that may present a risk to public health.
A substantially extended withdrawal period supported by appropriate scientific information (scientific literature, academia, or FARAD) must be established and followed. The client must maintain the identity of the animal treated, otherwise the entire group, herd or flock must follow the established withdrawal period.
Under the AMDUCA provisions, FDA has the right to prohibit extralabel uses of certain drugs in food animals if the extralabel use of the drug or class of drugs presents a risk to human health, including antimicrobial resistance.AMDUCA permits licensed veterinarians with a valid VCPR to prescribe extralabel uses (ELDU) of certain approved new animal drugs and approved human drugs under certain conditions per regulations.

“Minor use” drugs are for intended uses in major species (horses, dogs, cats, cattle, pigs, turkeys, and chickens) for diseases that occur infrequently or in limited geographic areas and in only a small number of animals annually.
“Minor species” are all animals other than humans that are not one of the major species. They include animals such as zoo animals, ornamental fish, parrots, ferrets, and guinea pigs. Some animals of agricultural importance are also minor species. These include sheep, goats, catfish, game birds, and honey bees among others.MUMS Act of 2004 The law is intended to make more medications legally available to veterinarians and animal owners for the treatment of minor animal species and uncommon diseases in the major animal species. ELDU of medicated feeds for Minor Use/Minor Species (MUMS) - CPG 615.115 According to the FDA, extra-label use of medicated feeds is illegal. This guide does not make extra-label use legal; it simply makes it less likely that action will be taken against veterinarians and producers who use medicated feeds approved for use in other species for therapeutic purposes in minor species under the conditions stated in the CPG. See Page 7 for the description of the ELDU written recommendation and the VFD “special instructions”.
