Three intervention strategies-trisodium phosphate, lactic acid, and sodium metasilicate--were examined for their in vitro antimicrobial activities in water at room temperature against a three-strain cocktail of Escherichia coli O157:H7 and a three-strain cocktail of "generic" E. coli. Both initial inhibition
