Ecolab Synergex™ First Product to Receive U.S. EPA No-Rinse Food Contact Surface Biofilm Claim

August 18, 2020

Helping food and beverage manufacturers increase food safety by killing food contact biofilms at no-rinse sanitizer levels

ST. PAUL, Minn.--(BUSINESS WIRE)-- Ecolab‘s Synergex™ is the first no-rinse product to receive U.S. Environmental Protection Agency (EPA) approval for efficacy against biofilms, a complex community of bacteria, on hard, non-porous food contact surfaces.

According to the EPA, biofilms form when bacteria adhere to environmental surfaces, especially those located in the presence of high moisture. Biofilms typically persist in a matrix containing slimy, glue-like substances which facilitate their attachment to many hard surfaces.1 

Although biofilms on food-contact surfaces were an unsolved issue for the food and beverage industry, there was no EPA-approved method to test sanitizer efficacy on biofilms. Ecolab, the global leader in water, hygiene and infection prevention solutions and services, partnered with the EPA to develop the first-ever food-contact biofilm test method.

Ecolab’s Synergex is an EPA-registered (EPA Reg. No. 1677-250) mixed peracetic acid (PAA) based sanitizer and disinfectant that helps food and beverage manufacturers enhance food safety, quality assurance, worker safety and air quality. Synergex has been developed to kill 99.9999% of Pseudomonas aeruginosa and Listeriamonocytogenes pathogens in biofilms on hard, non-porous food contact surfaces, at no-rinse sanitizer concentration level options.

“Biofilms are a leading cause of quality issues for food and beverage manufacturers, and until now, they have been difficult to eliminate on food-contact surfaces,” said Ann Gent, senior vice president and general manager of Ecolab Food and Beverage in North America. “Biofilms manifest in ways that mask the root cause of sanitation problems. A customer may see increased food spoilage or decreased shelf-life, for undetectable reasons. Synergex will help address the issues that result from biofilms on food-contact surfaces.”

“If biofilms are not killed during the cleaning and sanitizing process, bacteria and organisms are given a ‘head start’ to grow, allowing micro levels to exceed the quality threshold sooner in the food production process,” said Jesse Hines, technical accounts program leader for Ecolab Food and Beverage. “Biofilms are one of several microorganism challenges that can be handled using Synergex. The patented formulation of Synergex helps reduce day-to-day variability and promotes quality assurance.”
