3M Food Safety have added to its next generation 3M™ Molecular Detection Assays: the 3M™ Molecular Detection Assay 2 – Salmonella. This new test, enhanced with a proprietary 3M nanotechnology, provides customers with a streamlined workflow and simplifies their pathogen testing.

All 3M Molecular Detection Assay 2 tests – Salmonella, Listeria, and Listeria monocytogenes – use a single assay protocol, enabling batch processing of samples and improving efficiency in the laboratory. Incorporation of a unique color-change indicator provides increased confidence during the process. Compared to first generation tests, assay processing time is 30% faster and instrument run time is only one hour. Combined with short enrichment times, as low as 10 hours for 25g or composited 325g raw meat samples, these features give customers flexibility in their testing and allow them to make critical decisions faster.

The new test is a part of the award-winning 3M™ Molecular Detection System platform, used by food processors, universities, governments and contract testing laboratories in more than 40 countries. The 3M Molecular Detection System is 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 first generation assay for Salmonella, still available, was first offered in December 2011 when the system was introduced. In July 2015, 3M began to offer new assay technologies with test kits for Listeria and Listeria monocytogenes. All first and second-generation assays can be run simultaneously on the 3M™ Molecular Detection Instrument, making the transition to the new tests seamless.
