Sterilex Corporation is a recognized leader in developing anti-microbial, anti-biofilm, and decontamination products for the food processing, animal health, and water treatment industries. Sterilex PerQuat® technology is the first and only chemistry with products approved by the EPA to remove biofilm and kill biofilm bacteria in both public health and industrial use sites.

Case Study

Addressing Listeria Challenges in RTE Poultry Plant:

When a large fully cooked and deboned RTE poultry facility was experiencing periodic environmental Listeria positives, they contacted Sterilex. After Sterilex recommended the use of Sterilex Ultra Disinfectant Cleaner & Activator and Sterilex Ultra Powder dry floor sanitizer, the facility reduced Listeria positives by 80%.
