Environmental Listeria Plate

Product Description and Intended Use

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. The 3M Petrifilm EL Plates were designed to analyze environmental Listeria, consisting
of Listeria monocytogenes (L. monocytogenes), Listeria innocua (L. 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.
*For further information on the prevalence of Listeria species, please contact the 3M Food Safety representative
nearest you. Listeria ivanovii, Listeria grayi/murrayi and Listeria seeligeri grow but do not form typical colonies.
Many organisms in the environment can be stressed by environmental conditions or sanitizers. Buffered peptone water
is used as a repair broth in conjunction with the 3M Petrifilm EL Plate to resuscitate stressed Listeria without increasing
their numbers.
The 3M Petrifilm EL Plate components are decontaminated though not sterilized. 3M Food Safety is certified to ISO
(International Organization for Standardization) 9001 for design and manufacturing.
