Mere weeks after a U.S.-based Listeria outbreak linked to imported ricotta cheese affected 12 states, and resulted in 15 hospitalizations and three deaths the 3M Tecra Listeria Visual Immunoassay (VIA) for Environmental Testing (#091201) has received validation from the AOAC Research Institute’s Performance Tested MethodsSM Program. It allows food processors to monitor Listeria levels to identify hot spots within the plant and track progress. Using 3M Enviro Swabs or Sponges, the sample is collected and enriched before being placed in the assay where the results are read and interpreted. Providing results in just 48 hours, the VIA assures confidence in product safety while offering flexibility in the testing process.
