Head, Salmonella Reseach Laboratory, Bureau of Microbial Hazards

Current research and/or projects

Our goal is to understand the adaptations Salmonella uses to live on foods. We are interested in the relationships between the food environment and bacterial fitness/virulence/resistance. This information will help us assess and manage the risks associated with this pathogen.

Research and/or project statements

  • Incidence and levels of Salmonella in foods
  • Survival and growth of Salmonella in foods
  • Interventions to control for the presence of Salmonella in foods
  • Detection and spread of antibiotic resistance among Salmonella
