CompactDry LS - Listeria species

CompactDry LS - Listeria species

CompactDry LS is a ready-to-use, dehydrated chromogenic growth medium for enumeration and detection of Listeria species in food and drinks. Evaluation of surfaces and working environments is achieved by using the combination of CompactDry LS and CompactDry Swabs. Detection of Listeria occurs through the combination of selective agents and chromogenic substrates . Listeria species form light blue/blue colonies.

Listeria species are found in many environments such as soil, water, decaying vegetation, and animals. Certain species, such as Listeria monocytogenes, can survive refrigeration and other food preservation methods.

Listeria species can be transferred into the food chain when food is harvested / stored and can remain as a contaminant throughout the food production process. This requires continuous monitoring of raw materials, processed product, and the food production environment.
