| Abstract: | This study was conducted to test sanitizer efficacy of lactic acid on Salmonella typhimurium populations that were firmly attached or loosely attached on catfish skin with or without mucus. For both cell types, counts of S. typhimurium were reduced from 5.9 log10 CFU/skin to below the limit of detection of 2.0 log10 CFU/skin by a 5 min exposure to 2% lactic acid. Exposure for 1 min reduced a 104 CFU/skin inoculum to below the limit of detection. Catfish skin mucus slightly decreased the antimicrobial effect of lactic acid against firmly attached S. typhimurium. |
