This study systematically sampled retail poultry products every two weeks over the course of an entire calendar year and asked whether the prevalence of antibiotic-resistant E. coli differed by source and production category. In addition, we characterized brand-specific differences among E. coli isolates contaminating retail chicken products, making this study unique in its sampling intensity and its consideration of brand-level differences in resistance prevalence.

All available brands of retail chicken and turkey products were collected every two weeks from nine stores, representing each of the major grocery chains, in Flagstaff, AZ from January 2012 to December 2012. Data collected from each product included: store name, sell-by date, brand name, cut type, P-number (production plant number), special labels (e.g., organic, natural, raised without antibiotics, etc.) and a photo of the package. Products were refrigerated at 4 °C and processed no later than one day past their sell-by date.
