@entity526 isolates were recovered from the National Antimicrobial Resistance Monitoring System retail meat program and examined for antimicrobial susceptibility. Retail meat samples (n = 11,921) from four U.S. states collected during 2002 to 2008, consisting of 2,988 @entity1573 breast, 2,942 ground @entity233 , 2,991 ground beef, and 3,000 pork chop samples, were analyzed. A total of 8,286 @entity526 isolates were recovered. The greatest numbers of samples contaminated with the organism were @entity1573 (83.5%) and @entity233 (82.0%), followed by beef (68.9%) and pork (44.0%). Resistance was most common to @entity803 (50.3%), followed by @entity3639 (34.6%), @entity207 - @entity23174 (31.6%), @entity869 (22.5%), @entity801 (18.6%), @entity7913 (8.4%), @entity10188 (6.4%), and @entity3398 (5.2%). Less than 5% of the isolates had resistance to @entity206 , @entity2756 , @entity21563 , @entity802 , @entity2755 , and @entity2177 . All isolates were susceptible to @entity4509 . Compared to beef and pork isolates, the poultry meat isolates had a greater percentage of resistance to all tested drugs, with the exception of @entity2755 , to which pork isolates had the most resistance. More than half of the @entity233 isolates (56%) were resistant to multidrugs (>= 3 classes) compared to 38.9% of @entity1573 , 17.3% of pork, and 9.3% of beef isolates. The bla(CMY) gene was present in all @entity2756 - and @entity21563 -resistant isolates. The cmlA, flo, and catI genes were present in 45%, 43%, and 40% of @entity2755 -resistant isolates, respectively. Most @entity802 -resistant isolates (98.5%) had a gyrA mutation in S83 or D87 or both, whereas only 6.7% had a parC mutation in either S80 or E84. The results showed that @entity526 was commonly present in the retail meats, and antimicrobial resistance profiles differed according to the animal origin of the isolates.
