“…The presence and distribution of NTS serovars vary from region to region depending on the sampling plan and detection limits of the methodology employed. 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.…”

“…The rate of isolation of the different NTS serotypes was in agreement with the reports from previous research. 35,36 All the identified serotypes were isolated from both supermarket and butchery samples as well as whole carcasses and chicken parts at different rates ( Figure 1). This shows that the isolated Salmonella serotypes may be circulating within the environment and possible evidence is the fact that some of the products were contaminated with multiple NTS serotypes, which may also indicate varying sources of product contamination.…”

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.

“…Enteritidis) causes gastrointestinal disease in humans and is a major public health concern due to its ability to be transmitted via contaminated eggs or egg based and poultry meat products (Dominguez et al 2002). An approach to the control of S. Enteritidis is the use of bacteriophages, which have proven of value in the curtailment of S. Enteritidis infection in Cheddar cheese (Modi et al 2001), vegetables (Leverentz et al 2001), poultry products (Higgins et al 2005) and the skin of chickens (Goode et al 2003).…”

“…In this study, the MPN results determined that the chicken meat was a high microbialload food that preferred TT broth incubated at 439 C or RV broth in the enrichment step. The prevalence of S. enterica (18.7z) was higher (9,31) and lower (32)(33)(34) than that reported from other countries. In Thailand, a study reported a higher prevalence than that in this study (10).…”

SUMMARY:We assessed contamination by antibiotic-resistant bacteria in chicken meat obtained from supermarkets in Bangkok, Thailand. The prevalence of Salmonella enterica and Escherichia coli was 18.7z (14/75) and 53z (106/200), respectively. Most probable number (MPN) analysis showed that 56.7z of the samples (34/60) were in violation of the limit of allowable coliform bacteria in chicken meat, for which the maximum is 46,000 MPN/g. Multidrug-resistant phenotypes of both S. enterica and E. coli were found. The presence of class 1 integrons was demonstrated by polymerase chain reaction (PCR) and dot-blot hybridization. PCR showed that class 1 integrons were present in 42.9z (6/14) and 37.7z (40/106) of S. enterica and E. coli isolates, respectively. Resistance genes identified in this study were aadA2, aadA4, aadA22, and aadA23 (for aminoglycoside resistance); dfrA5 (for trimethoprim resistance), and lnuF (for lincosamide resistance). Four S. enterica isolates underwent multilocus sequence typing and the results were sequence type (ST) 50, ST 96, ST 1543, and ST 1549, which matched well with strains from many countries and reflected an international spread. Our study revealed that class 1 integrons have spread into community sources and might play an important role in horizontal antibiotic resistance gene transfer.
