Terentjeva M, Avsejenko J, Streikiša M, Utināne A, Kovaļenko K, Bērziņš A. Prevalence and antimicrobial resistance of Salmonella in meat and meat products in Latvia. Ann Agric Environ Med. 2017; 24(2): 317-321. AbstractIntroduction and objective. Salmonella is a foodborne pathogen which causes gastrointestinal illness in consumers, and exhibits resistance to antimicrobials of veterinary and clinical significance. The aim of this study is to detect the prevalence and 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 official control 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 antimicrobial resistance. The minimum inhibitory concentration (MIC) values were investigated in line with the requirements of the European 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 in minced meat and meat preparations (7/481), while the lowest (0%) in frozen meat and meat preparations (0/349) and RTE meats (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 resistant to sulfamethoxazole, 25% (5/20) to nalidixic acid, ciprofloxacin, ampicillin and 20% (4/20) to tetracycline. All isolates were susceptible to ceftazidime, cefotaxime, meropenem, azithromycin and tigecycline. S. Typhimurium exhibited antimicrobial resistance 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.

Epidemiological survey on the prevalence of Salmonella spp. in the Sardinian pig production chain, using real-time PCR screening method

“…The non confirmation of positivity at the microbiological analysis in the environmental samples not in contact with meat, that were positives at real-time PCR, shows the effectiveness of good hygiene practices during pre and post operative cleaning phases. Overall, data on the prevalence of Salmonella spp concerning environments, products and Salmonella typing obtained in this work confirm the ones reported in literature (D’ostuni et al , 2016; Terentjeva et al , 2017). As demonstrated by several research, our study demonstrated that the most common Salmonella serovariant isolated from pig in the EU are Salmonella Typhimurium, Salmonella Derby and monophasic serovariant of Salmonella Typhimurium (Bonardi, 2017; Barilli et al , 2018; EFSA and ECDC, 2016).…”

Occurrence and Antimicrobial Susceptibility Profile ofSalmonellaspp. in Raw and Ready-To-Eat Foods andCampylobacterspp. in Retail Raw Chicken Meat in Transylvania, Romania

“…Similar to our results, increasing AMR trends were published for TET in China [87.5% (Ren et al , 2017 ); 75.3% (Zhang et al , 2018 )], Thailand [73.3% (Sinwat et al , 2015 )], North Vietnam [58.5% (Thai et al , 2012 )] and the Czech Republic [100% (Myšková and Karpišková, 2017 )]; for SMX in Thailand (Sinwat et al , 2015 ) and Latvia (Terentjeva et al , 2017 ); for CIP in Latvia [24.0% (Terentjeva et al , 2017 )]; and for NAL in North Vietnam [28.8% (Thai et al , 2012 )]. Even if the recorded resistance level to another seven antibiotics, including AMP (35.3%), CHL (33.3%), TGC (25.5%), CTX (13.7%), CST (13.7%), TMP (7.8%), and GEN (2%) were moderate or low, the obtained results underscored a wide and worrying resistance spectrum of the Salmonella strains.…”

Prevalence of Salmonella in broiler chickens in Kagoshima, Japan in 2009 to 2012 and the relationship between serovars changing and antimicrobial resistance

“…This result is similar to those reported in other countries in Asia (Hyun-Jung [18, 19]), with S. Infantis as the main serovar. Although, the main serovar in some European countries was S. Typhimurium (Terentjeva et al [20], [21], Wierup et al [22]). The different Salmonella serovars present in broilers may depend on the region or country due to variations in climate, geographical regions and chicken husbandry practices among countries.…”
