David R. Smith, D.V.M., Ph.D., is a professor and Extension Dairy / Beef veterinarian in the School of Veterinary Medicine and Biomedical Sciences at the University of Nebraska-Lincoln. Earlier in his professional career he practiced food animal medicine and surgery. He is a board-certified veterinary epidemiologist with special interest in discovery and outreach regarding pre-harvest control of Shigatoxin producing Escherichia coli and Salmonella in cattle production systems. He also has research and extension activities in responsible use of antibiotics and methods to manage cattle populations to control the transmission of other pathogens important to cattle or human health, including Johne’s disease, BVDV, and neonatal calf diarrhea. He has served as the principle investigator of several large multidisciplinary studies of the ecology, and methods to control the transmission of E. coli O157:H7 in feedlot cattle. In 2005 he was awarded the Wendell Burgher Beef Industry Award. His professional memberships include the American Veterinary Medical Association, the American Association of Bovine Practitioners and the Academy of Veterinary Consultants. Dr. Smith has served on the AVMA Steering Committee on Antimicrobial Resistance, the AABP Committee on Food Quality, Safety and Security, and is currently a member and past-chair of the AVMA Food Safety Advisory Committee. He has served as President of the American Association of Extension Veterinarians and the Epidemiology Specialty of the American College of Veterinary Preventive Medicine.
Veterinary Epidemiology -especially the design of cattle production systems to improve animal, human, and environmental health
Use of field epidemiology to research the role of production-systems on the transmission of pathogens and the resulting impact on the health and productivity of dairy and beef cattle, and pre-harvest food safety.
Extension emphasis: communicating the principles of biosecurity and pathogen containment; emphasizing diagnostics and the role of production-systems on transmission of pathogens and the resulting impact on dairy and beef cattle health and pre-harvest food safety.
