3M Molecular Detection Assay for Listeria Receives AOAC PTM Validation

The 3M Molecular Detection Assay 2 – Listeria has been approved by the AOAC Performance Tested MethodsS program (Certification #111501). The approval certifies that this new second-generation test kit is equivalent or better than standard reference methods in the detection of Listeria spp. within a variety of food matrices and environmental surfaces.

Achieving AOAC PTM status required a rigorous, independent laboratory examination of 3M’s unique molecular test method’s ability to accurately detect Listeria spp. Food samples analyzed during the validation study included beef hot dogs, deli turkey, raw chicken leg pieces, raw chicken fillets, sealed concrete, plastic, stainless steel, melon, smoked salmon, romaine lettuce, queso fresco, vanilla ice cream, 4 percent milk fat cottage cheese and raw spinach.

The latest Listeria assay is one of three test kits that were expanded on the innovative 3M Molecular Detection System platform, designed around food processors’ needs for rapid pathogen detection and based on isothermal DNA amplification and bioluminescence detection technologies that provide a fast, simple testing method with high accuracy. The new Listeria test kit provides a reduced time to result – as little as 24 hours of enrichment – and features a streamlined workflow that is 30% faster than the first generation assay, originally launched with the platform in 2011, the company said.
