Tolerance of Salmonella enteritidis and Staphylococcus aureus to surface cleaning and household bleach.

The effectiveness of Five cloth types to reduce/eliminate Salmonella enteritidis and Staphylococcus aureus from stainless steel surfaces was compared. In general, S. enteritidis and S. aureus were still found on the surfaces at 0.6-2 log cfu/100cm2 when the surface had just been cleaned, with the exception of the antibacterial cloth in which bacterial counts were below the detection limit <0.6 cfu/100cm2. After cleaning the surface, the cloths contained bacteria at 104-105 cfu/100cm2 except for the antibacterial-treated cloth in which no bacteria could be detected. The effect of sodium hypochorite in suspension and in cloths was determined. Inactivation of bacteria in cloths required a higher concentration of sodium hypochlorite than in a suspension test. This study highlights the need for a hygiene procedure with cleaning cloths that prevents cross-contamination in the home. Journal of Food Protection 2003;66:2289-2295.
