NOVEL TECHNOLOGIES AND TECHNIQUES FOR THE DETECTION OF RESIDUES, TOXINS, AND OTHER CHEMICALS IN FOODS

The objectives include: 1) To develop laboratory-based multiclass, multiresidue analytical methods for veterinary drugs in animal-derived foods, feeds, and marker matrices (e.g., tissues, blood, urine); 2) to develop field-based instruments and methods for analytical screening of chemicals of food safety/security concern (or nutritional interest) in foods; 3) to develop field-portable and laboratory-based analytical methods for the screening and reliable identification of biotoxins and phytochemicals in foods; 4) devise a scientifically defensible and practical system to evaluate qualitative identification of chemical residues in complex matrices; and 5) employ and adapt progressive analytical concepts previously developed for pesticides (QuEChERS and related approaches) to meet other food safety and security applications (e. g. dioxins).
