Americas: 3M’s method receives validation

SHARE

3M’s molecular detection assay for Listeria monocytogenes has received validation with AOAC PTM status.

This means that 3M’s the next generation test kit is now equivalent or better than standard reference methods.

Achieving the 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).

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 isothermal DNA amplification and bioluminescence detection technologies and designed for a fast, simple and accurate real-time pathogen detection approach.

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.
