Two of 3M’s Molecular Detection Assays--Listeria monocytogenes and Listeria species--have been approved for First Action Official Method of Analysis distinction by AOAC International. The validations span a variety of food matrices including beef hot dogs, chocolate milk, cold smoked salmon, deli turkey and full fat cottage cheese. The assays provide rapid results after as little as 24 hours of enrichment--days faster than the standard methods.

The 3M™ Molecular Detection System, first introduced to food processors, third-party reference laboratories and other customers in 2011, is based on unique isothermal DNA amplification and bioluminescence detection technologies. The rapid, qualitative technology is applied to enriched food as well as food process environmental samples. It is designed around modern-day food processors’ needs for a real-time pathogen detection approach that’s faster and simpler while also more accurate.

“The AOAC Official Methods of Analysis carry a reputation for the highest standards of excellence and rigorous analysis, and we are proud that our assays are recognized by this globally-recognized agency,” said John David, global marketing supervisor with 3M Food Safety. “These validations further demonstrate 3M’s commitment to providing simple, rapid solutions that improve lab productivity while offering superior results.”

For its 3M Molecular Detection System, 3M also has AOAC International First Action Official Methods of Analysis status for its 3M Molecular Detection Assay Salmonella and both AOAC PTM and NF Validation by AFNOR Certification for its 3M Molecular Detection Assay Salmonella and 3M Molecular Detection Assay E.coli O157 (including H7), in addition to certifications from government and regulatory organizations in other countries around the world.
