Whole genome sequencing and other molecular subtyping methods are facilitating tremendous improvements in outbreak detection. However, these methods also having broader impacts and are providing insights into pathogen sources and persistence along the food chain. These findings are further emphasizing the importance of specific control strategies, such as control of pathogen persistence in processing plants. This presentation will provide an overview and case studies on the impact of whole genome sequencing and other “big data” type approaches on food safety and will also detail how finding from molecular subtyping studies have been used to achieve improved control of environmental pathogen sources.

Dr. Martin Wiedmann, Cornell University

Dr. Wiedmann received a veterinary degree and a doctorate in Veterinary Medicine from the Ludwig-Maximilians University in Munich in 1992 and 1994, and a Ph.D. in Food Science from Cornell in 1997. He currently is the Gellert Family Professor of Food Safety at Cornell. His research interests focus on farm-to-table microbial food quality and food safety and the application of molecular tools to study the biology and transmission of foodborne pathogens and spoilage organisms. He was a member of the Listeria Outbreak Working Group, which was honored by a USDA Secretary’s Award for Superior Service in 2000.  He also received the Young Scholars award from the American Dairy Science Association in 2002, the Samuel Cate Prescott Award from Institute of Food Technologists’ in 2003, the International Life Science Institute North America Future Leaders Award in 2004, and the American Meat Institute Foundation Scientific Achievement Award in 2011. He is a fellow of the Institute of Food Technologists (IFT), a fellow of the American Academy of Microbiology (AAM), and a member of the International Academy of Food Science and Technology.
