Abstract: This study aimed to elucidate the mechanism of ferrous and alkaline activated persulfate in inactivating Escherichia coli O157:H7 and Listeria monocytogenes. A five-strain cocktail of each pathogen was treated with activated persulfate for 5 min. The treated pathogens were plated on both selective and non-selective agars. DNA and protein leakage, TTC-dehydrogenase relative activity, and cellular ultrastructure were analyzed. The results showed there were significant (P
