Retail Meat Report, 2010. National Antimicrobial Resistance Monitoring System

摘要

The primary purpose of the NARMS retail meat surveillance program is to monitor the prevalence of antimicrobial resistance among foodborne bacteria, specifically, Salmonella, Campylobacter, Enterococcus and Escherichia coli. The results generated by the NARMS retail meat program serve as a reference point for identifying and analyzing trends in antimicrobial resistance among these organisms. The number of retail meat samples collected in 2010 totaled 5,280. Although there were no increases in total samples collected in 2010, the number of sites isolating meat samples for Escherichia coli and Enterococcus increased with the inclusion of the Maryland Department of Health laboratory. Improvements were made in reporting antimicrobial resistance trends. The Cochran- Armitage trend statistic was replaced by statistics calculated from binary logistic random effects regression models. To account for site variation, antimicrobial resistance over time was modeled with laboratory site as a random effect. Additional changes were made to the graphing of the prevalence of resistance over time allowing effortless retail meat and species comparisons.
