3M Food Safety's Molecular Detection Assay 2 – Salmonella has been approved for Official Method of Analysis by AOAC International (OMA method number 2016.01). The validation certifies that the test kit is equivalent or better than standard reference methods for the detection of Salmonella in a broad range of foods and food processing environmental surfaces.
The OMA consists of a multi-laboratory validation of the method, and subsequent review by an expert panel. Food matrices within the scope of the validation include raw ground beef, raw ground chicken, cooked breaded chicken, dry dog food, black pepper, raw whole shrimp, raw bagged spinach, pasteurized processed American cheese, chicken carcass rinse, chicken carcass sponge, instant non-fat dry milk, cocoa powder, pasteurized liquid whole egg, spent sprout irrigation water, creamy peanut butter, and sealed concrete, stainless steel and sealed ceramic tile environment surfaces. A complete review of the studies conducted for this validation will be published online by AOAC at http://eoma.aoac.org/ and in an upcoming edition of its Journal of AOAC International.
The 3M Molecular Detection Assay 2 – Salmonella offers short enrichment times, as low as 10 hours for 25g or composited 325g raw meat samples, giving customers flexibility in their testing and allowing them to make critical decisions faster, the company said. All four next-generation assays – Salmonella, Listeria, and Listeria monocytogenes, and E. coli O157 (including H7) – use a streamlined workflow that is 30 percent faster than the first generation, with fewer steps and a unique color-change indicator for increased control during assay processing. This results in fewer steps for today’s busy pathogen testing laboratories looking to enhance productivity, without compromising accuracy.
This Salmonella assay is a part of the 3M Molecular Detection System platform powered by a combination of advanced technologies — isothermal DNA amplification and bioluminescence detection — to provide a pathogen testing solution that is fast, accurate, easy-to-use and affordable, the company said.
