Efficacy of octenidine hydrochloride for reducing Escherichia coli O157: H7, salmonella spp., and listeria monocytogenes on cattle hides

Abstract

The efficacy of octenidine hydrochloride (OH; 0.025, 0.15, and 0.25%) for inactivating Escherichia coli O157:H7, Salmonella spp., and Listeria monocytogenes on cattle hides was investigated at 23°C in the presence and absence of bovine feces. All tested concentrations of OH were effective in decreasing more than 5.0 log CFU of bacteria/cm2 in 5 min (P<0.01). The results suggest that OH could be used to decontaminate cattle hides; however, further studies under commercial settings are necessary to validate these results. © 2012, American Society for Microbiology.
