Interpretive Summary:

Technical Abstract: A total of 3246 swine slaughter and 3147 swine diagnostic Salmonella isolates from the National Antimicrobial Resistance Monitoring System (NARMS) for the years 1997-2003 were tested for antimicrobial resistance. No resistance was detected in any Salmonella isolates for ciprofloxacin or amikacin. For all other antimicrobics tested, more resistance was observed in diagnostic isolates compared to slaughter isolates. In 2003, more than 50% of diagnostic isolates were resistant to 4 antibiotics: tetracycline (77.4%), streptomycin (75.5%), sulfamethaxazole (65.5%), and ampicillin (57.1%). Tetracycline (30.8%) was the antimicrobial with the most resistance in slaughter isolates. Continued monitoring of both slaughter and diagnostic isolates from swine are needed to demonstrate if changes industry use patterns of antimicrobials lead to changes in resistance patterns of Salmonella isolates from swine.
