The U.S. Food and Drug Administration has released its 2014 National Antimicrobial Resistance Monitoring System (NARMS) Integrated Report, highlighting antimicrobial resistance patterns in bacteria isolated from humans, retail meats, and animals at slaughter. NARMS monitors foodborne bacteria to determine whether they are resistant to various antibiotics used in human and veterinary medicine.
The prevalence of Salmonella in both retail chicken meat (9.1 percent) and retail ground turkey (5.5 percent) was at its lowest level since retail meat testing began in 2002. The prevalence of Campylobacter in retail chicken meat samples has gradually declined over time to 33 percent, the lowest level since testing began. Approximately 80 percent of human Salmonella isolates are not resistant to any of the tested antibiotics. This has remained relatively stable over the past ten years. Resistance for three critically-important drugs (ceftriaxone, azithromycin, and ciprofloxacin) in human non-typhoidal Salmonella isolates remained below 3 percent.
MDR Salmonella from turkey  Pathogen Reduction/Hazard Analysis Critical Control Point (PR/HACCP) samples has increased from approximately 27 percent to 41 percent over the past ten years.
High and increasing levels of ciprofloxacin resistance were detected in Campylobacter jejuni from human (26.7 percent) and chicken PR/HACCP samples (28 percent) in 2014, and remained above 35 percent in Campylobacter coli from humans.
