This 1-year survey was initiated in October 2006 to determine the prevalence of Salmonella serovars in retail chickens (conventionally and organically raised) obtained from Louisiana grocery stores, and to characterize the genotypes and antimicrobial susceptibility profiles of the Salmonella isolates.

From October 2006 to September 2007, a total of 194 whole chicken carcasses (conventionally raised, n 141; organically raised, n 53) were randomly collected from 27 retail grocery stores belonging to seven supermarket chains in Baton Rouge, Louisiana. These stores were identified from the supermarket chains’ official Web sites and consisted of 1 organic store and 26 conventional ones. Sampling visits were made every other week for a total of 25 times. On each sampling day, 3 randomly selected conventional stores and the single organic store were sampled. From each store, two (occasionally one) prepackaged, fresh, whole chicken carcasses were randomly selected and brought to the laboratory for analysis. A total of 14 chicken brands, with the majority of them being national brands, were involved in the sampling
