National Antimicrobial Resistance Monitoring System

According to the Report The 2010 NARMS (National Antimicrobial Resistance Monitoring System), for 2010, 5,280 retail meat samples were collected from 10 CDC FoodNet sites, including California, Colorado, Connecticut, Georgia, Maryland, Minnesota, New Mexico, New York, Oregon, Tennessee and the Pennsylvania Department of Health. Each site collected samples from a randomized list of area grocery stores.
For 2010, some 35 Salmonella Serotypes were distributed among 400 Salmonella positive samples. Of the 400 Salmonella positive samples, 171 (42%) were in found in Chicken Breasts, 202 (50.5%) were found in Ground Turkey, 7 (1.8%) were found in Ground Beef and 20 (5%) were found in Pork Chops. Of note, 43.3% of Chicken Breasts and 33.7% of Ground Turkey were resistant to more than 3 antibiotics.
For 2010, 3 types of Campylobacter were distributed among the 518 Campylobacter positive samples. Of the 518 positive samples, 505 (97.5%) were found in Chicken Breasts and 13 (2.5%) were found in Ground Turkey. Because of the low incidence of Campylobacter in Ground Beef and Pork Chops, no tests were performed.
NARMS also tested for Escherichia coli (could include Shiga-toxin producing strains but not necessarily) by meat type.  Of the 460 positives, Chicken Breasts - 460 (77.6%), Ground Turkey - 369 (80.2%), Ground Beef - 269 (58.5%) and Pork Chops - 183 (39.8%).
