Salmonella is a food-borne pathogen responsible about human salmonellosis cases. Meat and the products thereof were frequently found to be contaminated with Salmonella spp. in the previous studies. The aim of the present study was (i) to detect the prevalence of Salmonella in meat and products thereof in Latvia and (ii) to detect the antimicrobial resistance of the Salmonella isolates. Altogether, an amount of 3048 samples, including raw meat (n=522), minced meats (n=411), carcass samples (n=948) and meat preparations (n=1167) were collected from slaughterhouses and retail outlets in 2015. Samples were tested according to ISO 6579:2002. The antimicrobial resistance of Salmonella was detected in line with the EUCAST requirements. A total of 1.72% of raw meat and 0.95% of carcass samples were contaminated with Salmonella most frequently. Raw pork (7.14%) was the mostly found to be contaminated among the retail meats while the chicken carcasses (7.81%) were the most frequently contaminated among the slaughterhouse samples. All meat preparations and RTE meat samples were Salmonella – negative. The most common serovars were S. Typhimurium (36%), S. Derby (32%) and S. Enteriditis (12%). Other identified serovars included S. 58 Braederup, S. Give, S. Stanley, S. Wirchow and non-specified O:9,12. S. Typhimurium exhibited the antimicrobial resistance more frequently with resistance to ampicillin (38%), chloramphenicol (13%), gentamicin (13%), nalidixic acid (63%), ciprofloxacin (63%), tetracycline (25%) and sulfamethoxazole (50%). S. Derby showed the resistance less frequently and the resistance to tetracycline (25%) and sulfamethoxazole (25%) was identified. The results of the present study showed that the prevalence of Salmonella in meats still representing the public health concerns in Latvia.
