Prevalence and Enumeration of Antimicrobial Resistant Escherichia coli and Salmonella Throughout the Beef Production Continuum

The objectives of this research are to determine the prevalences and concentrations of extended-spectrum cephalosporin-resistant Salmonella and E. coli, quinolone-resistant Salmonella, and trimethoprim-sulfamethoxazole-resistant E. coli throughout the beef continuum from production, through processing, to final product and to determine the effectiveness of currently used processing interventions on the reduction of these antimicrobial resistant bacteria.
