Advanced Development of Innovative Technologies & Systematic Approaches to Foodborne Hazard Detection & Characterization for Improving Food Safety

Development and evaluation of technologies for sample preparation, detection (label-based and label-free), and characterization of microbial, chemical, and biological contaminants of concern in foods that can be implemented for improved food safety and food defense.1A. Spectroscopy-based identification of foodborne pathogens, toxins, and chemical contaminants.1B. Antibody-based detection of foodborne pathogens and toxins.1C. DNA - based detection of foodborne pathogens.1D. Phage-based detection of foodborne pathogens.1E. Cell-based detection of foodborne pathogens and toxins.1F. Enabling technologies for pathogen detection. 2: Application of CFSE developed technologies either alone or in combination with existing methods to evaluate microbial populations and the microbial ecology of foods during production and processing.2A. Expand the databases for BARDOT and HESPI techniques using pure cultures of known microorganisms (foodborne pathogens and indicator microorganisms).2B. Apply BARDOT and HESPI techniques to analyze microbial populations in foods.
