Technical Abstract: Background. Food associated enteritis from Salmonella has remained consistently higher than from other bacterial pathogens. Public health and regulatory agencies have therefore made reduction of Salmonella, including multiple antibiotic resistant strains, from chicken and other animal products a major priority.Methods. From 1999 through 2004, the prevalence and antimicrobial resistance profiles of Salmonella isolates from FSIS slaughter establishments submitted to the national antimicrobial resistance monitoring systems (NARMS) was determined. More than 40,000 isolates of Salmonella from FSIS slaughter plants were analyzed for antimicrobial resistance profiles using NARMS protocols and procedures.Results. In recent years, Salmonella recovery from chickens has increased from about 10% to 16% while in cattle, swine, and turkeys recovery has remained constant or has been slightly reduced. Single antibiotic or multiple-drug resistance in Salmonella is primarily associated with the serovar of Salmonella and secondarily associated with the Salmonella from a particular animal host species. Examples include: more antimicrobial resistance is seen in S. Typhimurium var 5- (formerly var Copenhagen) than from any other Salmonella serovar no matter the animal source; S. Typhimurium from turkeys carries more resistance than S. Typhimurium from other animals; very little antimicrobial resistance is seen in S. enteritidis regardless of source. Single and multiple antimicrobial resistance characteristics of Salmonella serovar from all animal sources will be discussed.
