In sync with leading industry standards, the new solution is being introduced with Performance Tested Method SM (PTM) certification from AOAC®INTERNATIONAL (Association of Official Analytical Collaboration).

Though Listeria makes fewer people sick than other foodborne pathogens, the presence of the bacteria is more pervasive andListeriosis carries a 20 – 30%* mortality rate if contracted by pregnant women, those over 65, or people with compromised immune systems (*Source:

A simple 24 hour + 24 hour enrichment process leverages supplemented standard media and incubation parameters are shared across matrices. Users can choose to process samples manually or automate them with Dynex Technologies’ DS-2® system.
