3M Food Safety’s Molecular Detection Assay 2-Listeria monocytogenes has been approved by the AOAC Performance Tested Methods program (Certification 081501). The approval certifies that the next generation test kit is now equivalent or better than standard reference methods.
It has earned matrix extensions from AFNOR Certification for its NF VALIDATION and is certified for samples taken from primary production as well as from animal feed and pet food.
Achieving AOAC PTM status required a rigorous, independent laboratory examination of 3M’s unique molecular test method’s ability to accurately detect Listeria monocytogenes within a variety of foods. Food samples analyzed during the validation study included beef hot dogs, queso fresco cheese, vanilla ice cream, 4% milk fat cottage cheese, 3% chocolate whole milk, romaine lettuce, bagged raw spinach, cold smoked salmon, deli turkey, raw chicken, cantaloupe, and various environmental surfaces (plastic, stainless steel, concrete).
Developed in response to customer engagement and ongoing desire to work with food processors to protect the world’s food supply, the latest Listeria monocytogenes assay is one of two test kits that were expanded on the innovative 3M Molecular Detection System platform. The 3M Molecular Detection System is based on unique isothermal DNA amplification and bioluminescence detection technologies and designed around food processors’ needs for a real-time pathogen detection approach that’s faster and simpler while also more accurate. The new test now provides a faster time-to-result – as little as 24 hours of enrichment – and features a streamlined workflow that is 30% faster than first generation assay.
