Abstract

Biocides have great relevance in the control of transmission of foodborne microbes through the food chain. In the present study, resistance to seven biocides was investigated among a collection of nine Escherichia coli strains, including verotoxigenic and beta-lactamase producers. The most effective biocides were triclosan, hexadecylpyridinium chloride and cetrimide, followed by benzalkonium chloride. Verotoxigenic and beta-lactamase producing strains did not show significant differences in their sensitivities to biocides compared to the other strains tested.
