Abstract

Currently, a “multiple-hurdle” approach based on a combination of different antimicrobial interventions, including heat, is being utilized during meat processing to control the burden of spoilage and pathogenic bacteria. Our recent study suggests that U.S. beef cattle harbor Escherichia coli that possess the locus of heat resistance (LHR).
