Producer Updates

Study Participation: We contact producers primarily through their veterinarians. Here is some information on the benefits we offer to participants, what our sampling involves for producers, and different ways to become involved.

Research Topics

  • Congenital hypothyroid dysmaturity syndrome in foals ("mustard" foals)
  • Foodborne Disease Overview: Researchers use epidemiology to understand Salmonella, E. coli O157 and Campylobacter. Outbreak investigations and long-term studies of pathogen movement on cattle farms help decrease the risk of foodborne illness. Our laboratory studies a variety of organisms which can be transmitted from cattle to humans.
  • The association of Feed and Water with Salmonella and E. coli O157 prevalence in cattle: A study funded by an FDA grant focuses on feed and water as sources of E. coli O157 and Salmonella infection
  • Salmonella: Investigating the epidemiology and ecology of Salmonella typhimurium DT104 in and around farms. The ultimate goal is to develop strategies to prevent entry of infection to the farm and to mitigate zoonotic risk
  • Escherichia coli O157 and Campylobacter: Studies on zoonotic bacteria Salmonella, Campylobacter jejuni and E. coli 0157. Recent human problems with E. coli 0157 have elevated the need for a descriptive epidemiology, determination of risk factors for herd status, and on farm ecology.
  • Mastitis: Heifer mastitis research includes identifying transmission factors, Staph. aureus epidemiology, immune response, milk antibody test, and management of dairy teat chapping.
  • Crooked Calf Disorder: Identifying the determinants for regional and on-farm variation in risk for lupine-induced arthrogryposis (crooked calf disorder) in range cattle.
