About

Dr. Debabrata Biswas is a Professor of Food Safety in the Department of Animal and Avian Sciences and the Center for Food Safety and Security Systems at the University of Maryland, College Park. He is a bacteriologist dedicated to developing crosscutting research programs in food safety. His research focuses on reducing levels of bacterial pathogens such as E. coli 0157, Campylobacter jejuni, and Salmonella enterica in food-producing animals and preventing cross-contamination in food processing plants to mitigate food safety risks for humans. Dr. Biswas investigates the role of natural products in controlling bacterial colonization in animal guts and explores mechanisms of their antimicrobial activity and survival in the presence of synthetic antibiotics or natural antimicrobial components. He also works on developing bioactive prebiotics, probiotics, and synbiotics as alternative therapeutic and growth-promoting components for organic and conventional farm animal production, aiming to stimulate beneficial bacterial growth and metabolite production. Additionally, his research includes developing efficient and rapid technologies for detecting foodborne enteric bacterial pathogens in food products and contaminated materials. His collaborative efforts span multiple disciplines, including Food Science, Biological Engineering, Plant, and Animal Sciences, to control enteric bacterial pathogens such as Salmonella, enterohemorrhagic E. coli (0157:H7), Listeria monocytogenes, and Campylobacter jejuni in foods and their animal reservoirs.
