Description of Research Interests
- Development of probiotic/competitive exclusion bacteria to reduce/eliminate carriage of E. coli O157:H7 by cattle and prevalence of L. monocytogenes in processing plants
- Ecology and reduction of carriage of Escherichia coli O157:H7 in cattle
- Detection and characterization of bacterial pathogens in food including E. coli O157:H7. Salmonella, Listeria monocytogenes, Campylobacter, Yersinia pestis, and Mycobacterium.
