Additional Information


The genus Listeria consists of six major species: L. monocytogenes, L. ivanovii, L. innocua, L. welshimeri, L. seeligeri, and L. grayi. Two species, L. monocytogenes and L. ivanovii, are considered pathogenic for animals, with L. monocytogenes being predominantly associated with human illnesses. All Listeria species are ubiquitously distributed in nature and can often be most often found in moist environments, such as soil, decaying vegetation, sewage, silage, dust, and water.
 
These procedures are able to detect if Listeria genus is present in a sample.
