3M has launched the 3M Molecular Detection System to help food processors to better respond to pathogens

London, Ont. – 3M has introduced the 3M Molecular Detection System.

The company says the new system can provide a fast, accurate, easy-to-use and cost-effective method for detecting dangerous foodborne pathogens, allowing the food processing industry to better respond to pathogens that can shut down businesses and threaten public health. The pathogens include Salmonella, E.coli O157 and Listeria spp.

The assay test kit for Salmonella received Health Canada’s approval in April 2013, and approval of the Listeria spp. assay test kit is currently pending.

The 3M Molecular Detection System is made up of a combination of unique technologies – isothermal DNA amplification and bioluminescence detection. It is a compact and robust system that is easy to use and maintain without compromising accuracy and reliability.


The 3M Molecular Detection System is sleek and compact – it has a smaller footprint than a laptop computer – making it highly portable and adaptable.

In operation, the system targets and amplifies nucleic acid in enriched samples to deliver highly sensitive results. The automated technology can evaluate produce, meats, processed foods, pet food and food processing-related environmental samples.

The 3M Molecular Detection System platform uses three individual, pathogen-specific assays, or procedural tests, that are sold as test kits: Salmonella (which is now accepted in the compendium of analytical methods), E.coli O157 (including H7), and Listeria Spp. Each assay test kit uses the same software interface and DNA extraction protocol, and can test between one and 96 samples per run.
