Foodborne Pathogens and Disease (2011)
Chicken products containing labels indicating that the chickens were not administered antibiotic or antimicrobial medications (no antibiotics added; n=201) and chicken products carrying conventional labels (n=201) were collected monthly from large retail food outlets throughout the state of Indiana from September 2009 to August 2010. Ten brands of chicken products were represented in the sample sets. Both sample sets included various cuts such as breasts, drumsticks, wings, wingettes, and thighs. Label information indicated that each sample within brand was processed on a different day.
The purchased samples were maintained at 4 degrees Celsius until processed. Each sample was ~100 g in size. Samples were processed as-is (skin was not removed, if present).
