The 3M™ Petrifilm™ Environmental Listeria (EL) Plate is a sample-ready-culture- medium system which contains selective agents, nutrients,a cold-water-soluble gelling agent, and a chromogenic indicator that facilitates colony enumeration and/or detection. Petrifilm EL Plates were designed to analyze environmental samples and to help increase the efficiency of monitoring plant sanitation. The Petrifilm EL Plate detects the majority of environmental Listeria, consisting of Listeria monocytogenes, Listeria innocua, and Listeria welshimeri.* The presence of indicator Listeria such as L. innocua provides evidence that environmental conditions are suitable for the occurrence of L. monocytogenes.
