Research Interests
Research and development of food safety interventions to mitigate contamination or growth of foodborne bacterial pathogens along the entire food continuum, from the farm to the fork. Bacteria of principal interest include Salmonella, Listeria monocytogenes, E. coli, and Campylobacter. Interventions include: (1) probiotic bacteria to reduce intestinal carriage of foodborne bacterial pathogens by cattle and poultry, and to reduce contamination of Listeria monocytogenes in food processing facilities, (2) antimicrobial wash treatments such as levulinic acid plus sodium lauryl sulfate that are bactericidal to pathogens but do not adversely affect the quality characteristics of foods, and (3) antimicrobial food preservatives such as novel organic acids in combination with antimicrobial synergists to suppress survival and growth of harmful bacteria in both raw and processed foods.
