Non-targeted Analysis for Food Safety Applications
Description:
Monitoring food for contamination is necessary to ensure consumer safety, but efforts are complicated by ever-expanding lists of emerging contaminants and the vast chemical space of unknowns. Contamination of food can occur from a variety of sources, including growing conditions (e.g., contaminated biosolids, soil, feed, water, agrochemical application), processing (e.g., equipment), packaging (e.g., additives and impurities), and preparation (e.g., cookware). Regulations have established maximum residue levels for a subset of known potential food contaminants, but non-targeted and suspect screening methods are needed to screen for contaminants of emerging concern and chemicals that lack standards or occurrence and toxicity information. Recent improvements to instruments, namely high-resolution mass spectrometers, and data processing tools have allowed for faster and more comprehensive screening capabilities. This session will focus on developments to non-targeted analysis (NTA) as it applies to areas of food safety. Possible topics include novel or improved NTA data processing techniques (e.g., software, instrument methods, peak prioritization), applications of NTA in food safety (e.g., contaminants in food or packaging, identifying transformation products), using NTA for (semi-)quantification, and statistical techniques, such as classification for adulteration monitoring.
Organizer: Raegyn Taylor - US Department of Agriculture, Agricultural Research Service
Biography: Dr. Raegyn Taylor is currently working as an ORISE Research Participant for the USDA Agricultural Research Service. In 2021, she received her PhD in Analytical Chemistry from Baylor University where her dissertation focused on the analysis of aquatic contaminants. This included optimizing passive samplers for pesticide analysis, evaluating pharmaceutical trends in wastewater during the COVID-19 pandemic, and monitoring algal toxins by targeted and non-targeted analysis. Her current research interests include assessing human exposure to emerging contaminants by improving sample preparation, data acquisition, and chemical prioritization techniques.
