FSIS is making available a list of test kits that have been validated for detection of relevant foodborne pathogens (i.e. Salmonella Campylobacter , E. coli O157:H7, Listeria spp. including L. monocytogenes , and non-O157 STECs). These lists are intended to be informational and are not an endorsement or approval of any particular method, regardless of its inclusion in the list.
