In this study we investigated the effects of low concentration electrolyzed water (LcEW) and several other sanitizers (strong acid electrolyzed water (SAEW) aqueous ozone (AO) 1% citric acid (CA) and sodium hypochlorite solution (NaOCl)) on the inactivation of natural microflora (total aerobic bacteria counts (TBC) and yeasts and moulds (YM)) and foodborne pathogens (Escherichia col, O157 H7 Listeria monocytogenes Salmonella Typhimurium and Bacillus cereus) on oyster mushroom The effects of temperature and treatment time on the antimicrobial activity of LcEW to reduce the populations of foodborne pathogens were also determined LcEW showed the strongest bactericidal efficacy among all the sanitizers on TBC YM and pathogens by reductions of 1 35 1 08 and 1 90-2 16 log CFU/g after 3 min treatment at room temperature (23 +/- 2 degrees C) respectively There was no significant difference between the antimicrobial effects of LcEW and SAEW (P>0 05) Among those sanitizers their relative influence of Inactivation was LcEW > NaOCl > CA > AO (C) 2010 Elsevier Ltd All rights reserved
