The objective of this study was to find alternatives to military field sanitation methods that will reduce the amount of greywater produced during sanitation operations and the logistical requirements of field sanitation. The cleaning and bactericidal efficacy of commercial-off-the-shelf COTS sanitizing wipes was tested on specially coated non-stick food contact surfaces, also under investigation by the Army. A biofilm was produced on the surfaces by soiling them with a food substrate contaminated by multiple strains of S. Aureus and E. Coli. One COTS wipe was effective on all four surfaces tested. The average counts of bacteria on Hycheck contact slides were reduced from too numerous to count per square inch before application of the sanitizing wipe gross food residues removed, to 0 to 11 colony-forming units per square inch after application of the sanitizing wipes. While effective on the four surfaces tested, it cannot be concluded that these wipes will clean and disinfect all surfaces found in a food service facility, or be reliable for removal of all possible soils and biofilms, without pre-cleaning the surface.
