Efficacy of Octenidine Hydrochloride for Reducing Escherichia coli O157:H7, Salmonella spp., and Listeria monocytogenes on Cattle Hides

Abstract

ABSTRACTThe efficacy of octenidine hydrochloride (OH; 0.025, 0.15, and 0.25%) for inactivatingEscherichia coliO157:H7,Salmonellaspp., andListeria monocytogeneson 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/cm2in 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.
