How has the veterinary feed directive changed dairy production medicine?
P. J. Gorden*1, 1Iowa State University, Ames, IA.

Antimicrobial residues in milk and meat from dairy cattle have long been scrutinized by the US public and governmental agencies as well as by the consumer. There are also increased concerns about the presence of elevated levels of antimicrobial resistance in both veterinary medicine and human medicine. Additionally, there is heightened fear that certain antimicrobial use practices in veterinary medicine are leading to decreased treatment efficacy in human medicine. As a result, the US Food and Drug Administration has issued several guidance policies in attempts to protect the effectiveness of medically important antimicrobials in human medicine. Due to the limited number of antimicrobials currently developed, many of these products crossover into veterinary medicine. One of the biggest changes the dairy industry has experienced in recent times related to antimicrobial use is the implementation of the Veterinary Feed Directive. As we move forward, the FDA expects that veterinarians will be more highly involved in decisions regarding antimicrobial stewardship on food production farms. Dairy farmers and their veterinarians must be progressively vigilant to make sure that public health is protected following consumption of products from dairy animals and that perception of milk and dairy beef remains as high as possible.

Key Words: Veterinary Feed Directive, antimicrobial stewardship

Speaker Bio
Dr. Patrick Gorden is a 1993 graduate of Iowa State University’s College of Veterinary Medicine.  After graduation, he joined the staff of the Platteville Veterinary Clinic (PVC), in Platteville, WI primarily doing dairy work.  While practicing in WI, he had an adjunct appointment with the Agriculture Department at University of Wisconsin – Platteville, teaching courses in Animal Science from 1996-2000.  While with PVC, the practice became one of the ambulatory practices for UW-Madison School of Veterinary Medicine. In 2000, Pat joined Dairy Veterinary Services (DVS), a 100% dairy practice in Chandler, AZ. DVS is a full service practice, serving farms ranging in size from 400-9000 cows.  In practice, Pat participated in all aspects of typical dairy practices, but his real passion is in the development of quality milk programs and milking equipment evaluation. During his tenure with DVS, he achieved board certification with the American Board of Veterinary Practitioners, certified in Dairy Practice. 
In 2007, Pat and his family relocated back to Ames, IA when he joined the faculty at ISU’s College Veterinary Medicine. He is currently a Clinical Professor, specializing in dairy production medicine, for the Department of Veterinary Diagnostic and Production Animal Medicine (VDPAM). In May 2010, he was appointed as Director of Food Supply Veterinary Medicine for VDPAM. He currently splits his time between providing clinical service to dairy clients, teaching dairy production medicine to veterinary students, collaborative research, and departmental administration.  In academia, his passion for milk quality and milking equipment performance has continued. However, quality milk programs have now morphed into the prevention of drug residues in milk and dairy beef; and the biology of drug metabolism in the health compromised cow. He is a frequent speaker at local and national veterinary and dairy industry meetings discussing the changing face of drug use expectations and the development of prudent drug use programs. He is currently working on his PhD focusing on drug metabolism in disease challenged animals.
Pat has been an active AABP member since veterinary school. He has served on the Milk Quality and Udder Health Committee, serving as committee chair for three years; and the ad-hoc Strategic Long Range Planning Committee. He currently serves on the Pharmaceutical and Biologics Committee and the Antibiotic Stewardship Task Force. has been the AVMA/AABP liaison to the National Conference of Interstate Milk Shipments (NCIMS) since 2012, where he serves on the Appendix N subcommittee, which develops drug testing programs for milk.  Also within NCIMS, he serves on the organization’s Executive Board as the University Liaison, being the first veterinarian to serve in this role. He is an active member in the National Mastitis Council and the National Institute for Animal Agriculture, serving as the Antibiotic Council Co-chair. 
Pat and his wife of 26 years, Kelly, are the proud parents of three typical teenagers.
