In food processing plants, the common sites for Listeria are floors, drains, conveyor belts, stainless steel equipment and cold rooms.
Listeria monocytogenes has a persistent ability to form biofilms matrices in the food processing environments. Biofilms are difficult to eradicate with chemical sanitizers, especially in areas with food debris.
BIOFILMS
PhageGuard Listex reduces Listeria populations in biofilms with 3 – 5 log/cm2. Unlike chemical sanitizers, which oxidize on the surface of the biofilms, phages are able to penetrate into the biofilms and kill Listeria from the inside.
PhageGuard can be used directly on the food, food contact surfaces or in the environment as an additional safety intervention against Listeria monocytogenes.
