2019 AOAC Annual Meeting - Preliminary Program

Multi-Class/Multi-Residue Veterinary Drug Methods: Which Strategies and for what Purpose? In recent years, the needs and interests on multi-class/multi-res- idue veterinary drug methods have been growing quickly in the scientific community of chemical contaminants for the purpose of increasing sample throughput and improving monitoring program efficiency. Progresses have been made in terms of developing and validating multi-class/multi-residue methods aiming at quantifying or screening over 100 veterinary drugs in a single analysis. This scientific session brings the latest develop- ments from the scientists in the field on their recent achievements on the development of multi-class/multi-residue methods that are based on target or non-target data acquisition for target analysis (screening and quantification) of veterinary drugs in food using liquid chromatography coupled to low resolution (LR) or high resolution (HR) mass spectrometry. The discussions and presen- tations not only include topics on targeted versus non-targeted screening approaches, multi-class screening with LR versus HR mass spectrometers but also method validation guidelines and the method performance criteria, especially for screening based on high mass-resolution mass spectrometry.

Traditional biochemical identification techniques are being supplemented with molecular biology techniques, using genomics, bioinformatics, and proteomics. These sciences are producing both methods and results that are now represented in the AOAC OMA, FDA Bacteriological Analytical Manual, and the USP Food Chemicals Codex. The resulting information is adding insight and revelations, and causing the occasional change, to the existing classification and taxonomy. As methods advance, industry’s knowledge of these methods must advance as well. In order to assure the analytical communi- ties’ confidence in molecular methods for bacterial identification, Microbial Identification with Genomics and Proteomics in Food and Dietary Supplements

both methods and equipment used to produce results must be well understood. This session will be sponsored by, and feature speakers from AOAC Research Institute, global food manufacturer Herbalife Nutrition, as well as feature speakers from food-targeted equip- ment manufacturers. These speakers will present the applications of molecular methods for bacterial identification, which will be useful for food and dietary supplement industry professionals.
