Genetically Modified Vaccines Are Given To Organic Livestock

By On August 8, 2017

Did you know that genetically engineered vaccines are approved for use on the organic livestock you are likely feeding your family?

The USDA National Organic Program “identifies all vaccines, as a group, as synthetic substances allowed for use in organic livestock production. Vaccines are not individually listed on the National List, but rather are included on as a group of synthetic substances termed “Biologics Vaccines,” that may be used in organic livestock production.”

The U.S. Food and Drug Administration (FDA) has issued a letter reminding retail establishments that sell medically important antimicrobials for use in feed or water for food animals that the marketing status of those products will change from over-the-counter (OTC) to prescription (Rx) or to veterinary feed directive (VFD) at the end of calendar year 2016. Once the changes are in place, distributors of those medically important antimicrobials will need to comply with appropriate requirements for Rx and VFD drugs when dispensing these products. The letter also provides retail establishments with recommendations for addressing current and future inventory of medically important antimicrobials for use in feed or water for food animals.

In December 2013, the FDA took a significant step forward in addressing antimicrobial resistance by publishing Guidance #213, which calls on animal drug sponsors of approved medically important antimicrobials administered through medicated feed or water to remove from their product labels indications for use related to growth promotion, and to bring the remaining therapeutic uses of these products under the oversight of a veterinarian by the end of December 2016. All of the affected drug sponsors notified the FDA of their intent to make the recommended changes to their products within the established timeframe.

By January 1, 2017, the FDA expects all drug sponsors will complete the necessary label changes of their affected products and then changes in drug use practices will begin. The marketing status of affected drugs will change from OTC to Rx status for drugs administered through drinking water or to VFD for drugs administered in medicated feeds. Distributors or retail establishments that handle these products will be required to meet all applicable State and Federal regulations for Rx and VFD drugs when dispensing these products.

In addition, the FDA recently published the VFD final rule, which outlines the revised process for authorizing use of VFD drugs (animal drugs intended for use in or on animal feed and that require the supervision of a licensed veterinarian). The VFD rule also provides veterinarians in all U.S. States with a framework for authorizing the use of medically important antimicrobials in feed when needed for specific animal health purposes. The VFD final rule became effective on October 1, 2015 and includes specific requirements for distributors of these products.

Additional information regarding the products that are transitioning from OTC to Rx or VFD marketing status and requirements for retail establishments is provided in the Retail Establishment Letter, dated June 17, 2016.
