摘要：Introduction and objective. Salmonella is a foodborne pathogen which causes gastrointestinal illness in consumers, andexhibits resistance to antimicrobials of veterinary and clinical significance. The aim of this study is to detect the prevalenceand antimicrobial resistance of Salmonella isolates from meat in Latvia.Materials and method. A total of 3,152 samples of raw and ready-to-eat (RTE) meats were collected during the officialcontrol and in-house control procedures in 2015. Samples were tested in accordance with ISO 6579:2002. All S. Typhimurium,S. Enteritidis and other isolates recovered from the official control samples (S. Derby, S. Give) were tested for antimicrobialresistance. The minimum inhibitory concentration (MIC) values were investigated in line with the requirements of theEuropean Committee on Antimicrobial Susceptibility Testing (EUCAST).Results. The prevalence of Salmonella was 0.8% (25/3152). The highest prevalence (1.5%) of Salmonella was found inminced meat and meat preparations (7/481), while the lowest (0%) in frozen meat and meat preparations (0/349) and RTEmeats (0/364). The most common serovars were S. Typhimurium (36%, 9/25) and S. Derby (32%, 8/25). In total, 62% (13/21)of Salmonella isolates were resistant to at least one antimicrobial agent. Altogether, 40% (8/20) of isolates were resistantto sulfamethoxazole, 25% (5/20) to nalidixic acid, ciprofloxacin, ampicillin and 20% (4/20) to tetracycline. All isolates weresusceptible to ceftazidime, cefotaxime, meropenem, azithromycin and tigecycline. S. Typhimurium exhibited antimicrobialresistance more often (87.5%) than other serovars.Conclusion. The study shows that the presence of Salmonella in meat, together with the high prevalence of resistant strains,is a significant public health related issue in Latvia.
