Development of a sanitizing fabric wipe for use on food contact surfaces.

A sanitizer was incorporated into disposable sanitary wipes that were used to eliminate microorganisms on plastic and metal surfaces. These surfaces were inoculated with strains of Bacillus subtilis OSU 494, Enterococcus faecalis OSU 48, Escherichia coli ATCC 29181, Listeria innocua ATCC 33090, Pseudomonas aeruginosa OSU 167, Salmonella enteritidis OSU 799, Staphylococcus epidermidis OSU 838), Candida albicans ATCC 10231, and Aspergillus fumigatus ATCC 10894. These inoculated surfaces were cleaned with the wipes for 5, 10, and 30 s, then organisms surviving on the cleaned surfaces and in the wipes were enumerated. Applying the sanitizing wipe to the plastic and metal surfaces reduced the viability of bacteria (> log 4 for 5 s), yeast cells (> log 5 for 10 s), and fungal spores (< log 4 for all times). The use of large pore sized or thick wipes showed better sanitizing result when compared with the use of the small pore sized and slim wipe. There were no significant differences (P > 0.05) between surviving numbers on the surface of the plastic compared with that of the metal.
