Sanitizer efficacy against bacteria attached to synthetic meat processing surfaces
The effectiveness of selected sanitizers against bacteria attached to synthetic meat processing surfaces was determined. In initial experiments, in vitro suspensions of Shw. putrefaciens, P. fragi, S. typhimurium, and L. monocytogenes were challenged with sanitizers according to the AOAC Germicidal …

EVALUATING METHODS OF CLEANING AND CLEANING VERIFCATION FOR THE REMOVAL OF ENVIRONMENTAL PATHOGENS IN FOOD PROCESSING PLANTS
… from U.S. food processors. We found that sanitizer tolerance genes and other environmental stress adaptations were common but didn’t find evidence for their contribution to environmental persistence. These findings do not support the conclusion that food processing facilities should change …

Factors Influencing The Ecology and Epidemiology of Microbial Indicators and Foodborne Pathogens In Surface Waters and Development of Risk Mitigations
… determine the efficacy of chemical antimicrobial sanitizers against Salmonella in pre-harvest agricultural water. Results demonstrated that certain sanitizer treatments and conditions can significantly reduce Salmonella populations in preharvest agricultural water sources and thus may serve as a …
