3M Microbiology's 3M Petrifilm Environmental Listeria Plate has been validated by the AOAC Research Institute for the detection of Listeria on environmental surfaces in food processing plants. The EL Plate gets quantitative results that provide an indication of the level of contamination instead of simply identifying presence or absence. This information enables plants to identify contamination sources and track hot spots or growth niches over time. The results are available 29 hours after sample collection.
