During this half-day workshop, attendees will learn (or re-learn) the basics of finished food product testing with a focus on three-class plans to identify and enumerate the foodborne pathogen, Listeria monocytogenes. Participants will gain insights through a comparative study of currently used methods versus enumerative approaches, particularly in food products considered as low-risk (because they do not support growth) for the presence of Listeria monocytogenes. This workshop is crucial for attendees as it highlights the importance of collecting both qualitative and quantitative data to enhance risk management decisions. With USDA and FDA’s zero action limits for Listeria monocytogenes, we have collectively missed over a decade of valuable data that could inform better decision-making processes. By understanding and applying three-class sampling and testing plans, attendees can contribute to a more nuanced approach in identifying the prevalence and levels of Listeria monocytogenes in different foods. This renewed approach not only aids in complying with regulatory requirements but also plays a vital role in the continuous improvement of food safety practices.
