Comparison of antimicrobial efficacy of multiple beef hide decontamination strategies to reduce levels of Escherichia coli O157:H7 and Salmonella.

This study involved a comparison of the antimicrobial efficacy of several beef hide decontamination interventions to identify those that more effectively reduced levels of Escherichia coli O157:H7 and Salmonella. Whole beef hides were inoculated with E. coli O157:H7 and Salmonella and decontaminated with sprays of solutions of acetic acid (AA; 10%, 55 degrees C), lactic acid (LA; 10%, 55 degrees C), sodium hydroxide (SH; 3%, 23 degrees C), sodium metasilicate (SM; 4%, 23 degrees C), or sodium hydroxide (1.
