New Zep Biofilm Drain Purge Kills Harmful Microorganisms

First Biocide Approved by EPA to Kill Biofilms in Drains and Trunk Lines

ATLANTA (February 10, 2009) – The food industry now has a way to attack harmful Listeria, E. coli, Salmonella and other resistant microorganisms in hard-to-reach drain and trunk lines.  New Zep Biofilm Drain Purge effectively cleans organic debris from drains and piping, killing harmful bacteria that cause odors and illness.

Drains and trunk lines have been shown to be a breeding ground for resistant pathogens such as Listeria, E.coli and Salmonella, which form protective biofilms in wet environments.  In fact, a 2004 audit of food processing facilities by the USDA Food Safety and Inspection Service reported that 27.8 percent of floors and drains sampled tested positive for Listeria.

“The USDA recommends that processors work with sanitation suppliers to develop a sound floor and drain sanitation program,” explains Blaine Morton, director of marketing and business development, Food, Zep Inc..  “Zep’s new Biofilm Drain Purge is the newest part of Zep’s complete food sanitation program, designed to ensure a safe, contamination-free food operation.”

Eliminating Biofilms

The problem with biofilms is that they tend to persist in damp areas, allowing pathogens in drains and trunk lines to become resistant to chemical and heat treatment.  Without removing the biofilm matrix, it is impossible to kill pathogens.

Zep Biofilm Drain Purge has advantages over typical drain cleaners such as enzymatic cleaners, drain openers and quat-based sanitizers that do not have EPA approval to kill biofilm and are ineffective against typical pathogens in biofilms.  It attacks the biofilm, penetrating and removing it while acting as a bactericide, slimicide and algicide.

Zep Biofilm Drain Purge is easy to use.  It may be applied as a foam or a liquid and is “self-scrubbing” when activated, eliminating the need to manually scrub surfaces, thus reducing labor.  It is available in 5 gallon and 55 gallon drums.  Zep also supplies manual and air-operated foamers to apply the product.
