Foodborne illness in the United States is an important health concern. Outbreaks highlight key deficiencies in the food distribution chain, and one of them is the lack of traceability methodology to track contaminated food back to the source in a time effective manner. One of the four critical areas under the FDA Food Modernization Safety Act is the need for better detection of and response to food safety problems. Common food testing strategies include traditional bacterial culture/plating of food samples to test for bacterial pathogen contamination, as well as advanced testing options including DNA and immunology-based assays. While these assays are sensitive and reliable, they suffer from key limitations including: the inability to to reliably distinguish viable bacteria in food samples, a requirement for comprehensive sample and assay preparation which in some cases requires 3-7 days to obtain a result, etc.
University and USDA scientists have been working to develop technologies that will enhance the ability to sample and test increasing amounts of foods as well as improve the detection and analysis of of foodborne pathogens. This webcast highlights several technologies including a light scanner imaging technology called BARDOT, for detection and analysis of foodborne pathogens, immobilized bacteriophage, FT-IR methods, and high-throughput biosensors for multiplexed foodborne pathogen detection.

To date Prof. Bhunia has published 123 refereed articles, 2 text books (Fundamental Food Microbiology; Foodborne Microbial Pathogens: Mechanisms and Pathogenesis), 2 edited books, 15 book chapters, 33 proceeding articles, 137 research abstracts, and delivered more than 84 invited talks, keynote and plenary talks in national and international meetings, served on review panels for federal grants, and chaired sessions in national and international meetings. He was awarded two patents, and received Purdue Agriculture Research Award (2003), Purdue Faculty Scholar (2005), Purdue Team Award (2006), IFT R&D Award (2009), and Outstanding Graduate Educator Award in the Department of Food Science at Purdue (2010).
Dr Michael Ladisch
Michael R. Ladisch is Director of the Laboratory of Renewable Resources Engineering (LORRE), and Distinguished Professor of Agricultural and Biological Engineering, with a joint appointment in the Weldon School of Biomedical Engineering, and a courtesy appointment in Food Science. His BS (1973) is from Drexel University, with MS (1974) and PhD (1977) from Purdue University, all in Chemical Engineering. He is continuing his activities with Mascoma Corporation where he has been Chief Technology Officer since 2007.
Dr. Ladisch has 35 years experience in research in biofuels, renewable resources, and biotechnology. He has authored a graduate textbook (Bioseparations Engineering, Wiley, 2001), and co-authored an undergraduate textbook (Modern Biotechnology, Wiley, July, 2009), as well as 30 book chapters, 233 research papers, 56 Proceedings Chapters and Extended Abstracts 181 journal publications, and 20 patents granted or applied for. He has given 207 papers, invited lectures, and presentations at national and international meetings. He was a member of the Alternative Liquid Transportation Fuels Panel and chaired the Bioprocess Engineering sub-group of the US National Academies that recently published a report on this topic in 2009.
Dr. Ladisch’s research includes bioprocess engineering, transformation of renewable resources into biofuels and bioproducts, and food safety. His fundamental studies address properties of proteins and living organisms at surfaces, microfluidic biosensor systems, bionanotechnology and bioseparations.
The American Institute of Chemical Engineers awarded him the Food, Pharmaceutical and Bioengineering Division Award in 2001, and named him as one of the 100 engineers of the Modern Era in 2008. He received the Marvin J. Johnson Award in Biochemical Technology of the American Chemical Society in 2002, the Paul Dana Biofuels Award in 2006, and the Agricultural Team (Biosensor Detection Team) and Outstanding Chemical Engineer Awards at Purdue University in 2006. He received the Charles Scott Award of the Society of Industrial microbiology in 2009. He was named a fellow of the ACS and AAAS in 2011. Dr. Ladisch was elected to the National Academy of Engineering in 1999.
