“…36 Butchery products were more contaminated with NTS (32%) than supermarket products (18%). This result, though contrary to the report by Yang et al 37 , was in agreement with the findings of Chaiba et al 35 and could be the result of better hygienic standards maintained in supermarkets than butcheries. Frozen products had a higher NTS recovery rate (10.4%) than fresh products (8.8%).…”

This study was conducted to evaluate the incidence of non-typhoidal Salmonella (NTS) serotypes in raw and ready-to-eat (RTE) broiler products in the North West Province of South Africa. A total of 120 raw broiler samples, 40 samples of polonies and 20 samples of smoked viennas were obtained from retail points in major cities and towns in the province. Samples were subjected to aerobic plate count and later screened for the presence of NTS using phenotypic and genotypic techniques. The average bacterial count in raw products was 3.1 x 10 5 cfu/g whereas bacterial contamination of RTE products was 1.8 x 10 3 cfu/g. The average recovery rate of NTS species from raw broiler products was 12.5% and the serotypes identified were S. typhimurium (46.4%), S. enteritidis (30.9%) and S. newport (22.9%). No NTS was recovered from the RTE products. However, S. typhimurium was the predominant serotype in whole carcasses whereas S. enteritidis and S. newport were prevalent in chicken parts. Out of the 160 presumptive NTS isolates screened by polymerase chain reaction (PCR), 140 (87.5%) were confirmed for the presence of the Salmonella-specific invA gene. In addition, 115 (82.4%) of the confirmed isolates harboured the plasmid spvC gene. Random Amplified Polymorphic DNA (RAPD) fingerprinting of isolates using RAPD 1 and RAPD 3 primers, revealed some inter-and intra-serotype genetic diversity among isolates, suggesting varying sources of contamination. The results of this study represent the first report on the incidence and prevalent serotypes of NTS in chicken products in the North West Province of South Africa.

“…Interestingly, the overall incidence level of Salmonella (17%) from broilers was close to that (21.99%) reported earlier in Bangladesh [22]. Many studies showed different prevalence rates of Salmonella isolates in broilers worldwide: in Brazil, a low rate of 2.7% was reported [23], while in China, a high rate of 52.2% was reported [3]. These differences in prevalence rates may reflect considerable disparity in the sampling scheme, sample types, Salmonella detection protocol, and geographic location.…”

“…This is a cause for concern to public health authorities, owing to the associated risks of bacterial food poisoning [2]. Furthermore, poultry have always topped the list of foods associated with incidences of salmonellosis in many developing countries including India, Egypt, Brazil, and Zimbabwe [3].…”

Introduction: Salmonella serovars are one of the primary foodborne pathogens. Poultry consumption is responsible for the majority of disease cases worldwide. The prevalence of virulence determinants among Salmonella serovars appears to be lacking in Egypt. Therefore, this study investigated the occurrence, antibiotic resistance patterns, and virulence gene profiling of Salmonella serovars in broilers. Methodology: Three hundred samples from broiler chickens were examined for the presence of Salmonella by standard microbiological techniques. All Salmonella isolates were tested for their sensitivity against ten antibiotics and subjected to virulence genotyping by polymerase chain reaction (PCR). Results: The overall isolation percentage of Salmonella was 17%. Seven different serovars were found, with the main one being Salmonella Typhimurium (52.94%). Salmonella isolates were sensitive to most of the tested antibiotics, but they exhibited absolute resistance against amoxicillin/clavulanic acid. Nine Salmonella strains (52.94%) were resistant to at least three antibiotics. Further PCR investigations into 17 Salmonella strains revealed different distribution patterns of eight virulence determinants among the isolates. The invA gene was the most prevalent one (100%), followed by hilA (88.24%), stn (58.82%), and fliC genes (52.94%), while each of sopB and pefA genes had a similar prevalence (41.18%), and sefC and spvC genes had the lowest prevalence (11.76 and 5.88%, respectively). PCR genotyping allowed grouping of Salmonella strains into ten genetic profiles. Conclusions: These results will help in understanding the spread of virulence genotypes and antibiotic resistance among Salmonella serovars in broilers.

“…The Salmonella isolation rate for meat samples collected from the supermarket (37%) was similar to that of samples recovered from the wet market (45%). Salmonella isolates were recovered from 45 pork samples and 16 chicken samples at rates of 56% and 23%, respectively, which are recovery rates much higher than those of other countries but similar to those in a recent study from China (16)(17)(18). Since some of the samples contained two Salmonella isolates, a total of 112 Salmonella strains were collected for further characterization; among these 112 strains, 86 were isolated from pork and 26 were isolated from chicken.…”

Food-borne salmonellosis is an important public health problem worldwide and the second leading cause of food-borne illnesses in Hong Kong. In this study, the prevalence and antimicrobial resistance of Salmonella in meat products in Hong Kong were determined. Interestingly, a plasmid-mediated quinolone resistance (PMQR) gene combination, oqxAB, which mediates resistance to nalidixic acid, chloramphenicol, and olaquindox, was for the first time detectable on the chromosomes of two Salmonella enterica serovar Derby isolates. Further surveillance of oqxAB in Salmonella will be needed.
