| Popis: | The use of sanitizers during produce wash operation is a common practice, but little is known about the effect of residual sanitizers on minimizing food safety risks associated with post-sanitizing cross-contaminations. This study investigated the effect of residual chlorine and organic acids on the survival and the attachment of E. coli O157:H7 and L. monocytogenes on spinach leaves during refrigerated storage. The pathogens were spot inoculated on chlorine (100 ppm), lactic acid (0.5%) and acetic acid (0.5%) treated leaves, and their survival during refrigerated storage (4 °C) was examined. A significant reduction (P |
