Six strains of L. monocytogenes and one strain of L. innocua were attached to stainless steel or aluminum coupons that had been cut from a used deli meat slicer. One cleaner/sanitizer and two sanitizers were tested against the attached cells. No sanitizer caused more than a 1.5 log CFU/cm2 reduction of Listeria when treated and untreated coupons were compared. Many delicatessens are using sanitizing wipes during operating times. Therefore, the best performing sanitizer, sanitizer C, from the first experiment was applied with a variety of cleaning cloths and compared with a commercial sanitation wipe. No cloth produced more than a one log reduction compared to controls.

However, 89% of listeriosis patients were hospitalized and there was an overall 12.7% case fatality rate (CFR), in contrast to 27.5% hospitalizations and a CFR of 0.34% for salmonellosis (2). Consumption of food contaminated by L. monocytogenes is the primary mode of transmission of this pathogen to humans (7). L. monocytogenes contaminates food from a variety of environmental sources and food processing facilities. If present in meats or cheese, L. monocytogenes can contaminate slicers in delicatessens, and the resulting contaminated food contact surfaces may allow bacterial survival and multiplication and thus become sources of cross-contamination of 68 FOOD PROTECTION TRENDS | FEBRUARY 2012 http://www.foodprotection.org/files/food-protection-trends/Feb-12-Crandall.pdf
