FDA Video Outlines Drug-resistance in Parasites

Dr. Aimee Phillippi-Taylor hosts the video, which stresses the value of using fecal egg count reduction tests and record keeping to detect resistance in parasite populations. 

A new video from the FDA’s Center for Veterinary Medicine (CVM) provides a basic explanation of drug resistance in livestock and management practices for retaining efficacy of products used on a farm.

Aimee Phillippi-Taylor, DVM, introduces the video, which describes how continued use of antiparisitic drugs can result in emergence of resistance. In addition to basic management, the video encourages producers to work with their veterinarians in conducting fecal egg count reduction (FECR) tests to monitor the efficacy of deworming programs and adjusting as needed. The video also stresses that the value of tailoring an overall parasite-control program based on the farm’s production environment and management practices

The video, intended as an introduction to the topic, does not explore more complex strategies such as refugia, which involves leaving some portion of a herd untreated to maintain a dominant population of drug-susceptible parasites.
