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 Safety Modernization 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 will highlight several technologies including a cell concentration and recovery device; light scanner imaging technology called BARDOT, for detection and analysis of foodborne pathogens; high-throughput biosensors for multiplexed foodborne pathogen detection; and USDA research activities.

Learning Objectives:

  • Participants will examine technologies developed for the rapid detection and analysis of foodborne pathogens
  • Participants will learn about USDA and university applications of the rapid detection technologies for analysis of pathogens from foods
