Salmonellae are highly pathogenic foodborne bacteria able to cause infection even at low doses. Infection by Salmonella from contaminated foods leads to gastrointestinal disease known as salmonellosis. Raw chicken can be a source of human infection if the meat products are not properly handled, stored or cooked. The aim of the present study was to investigate the prevalence of Salmonella Enteritidis and Salmonella Typhymurium serovars in retail raw chicken meat from retail market in Erbil, as well as, to assess their antimicrobial resistance. A total of 100 raw retail chicken meat samples were collected and plating on Xylose Lysine Deoxycholate and Salmonella-Shigella agar media. In addition, the typical black colonies were identified and stored for further analysis. In addition, Salmonella spp. isolates recovered from the samples were identified and tested for antibiotics susceptibility by using VITEK 2 automated system. The multiplex polymerase chain reaction was employed to detect Salmonella Enteritidis and Salmonella Typhymurium in the meat samples. Out of 100 raw chicken meat analysed samples, 5 (5%) were positive for Salmonella Typhimurium, while none of the samples were contaminated with Salmonella Enteritidis. The resistance levels of the isolates against 12 different antimicrobial agent were tested: all the strains were suscebtible to Imipenem, Meropenem, and Ciprofloxacin. However, the resistance rates in the bacterial isolates were 20% each for Amikacin, Gentamicin, and Tobramycin, also 40% and 30% resistance for Minocycline, and Trimethoprim/Sulfamethoxazole. All isolates of the Salmonella Typhymurium were multiresistant to three or more antimicrobial agents. Preventive measure such as proper temperature control as well as proper handling of raw chicken meat in the market place are crucial to the minimization of any potential health hazard by this foodborne pathogen.

Introduction: Salmonella enterica serovars Enteritidis and Typhimurium represent the major serovars associated with human salmonellosis. Contamination of meat products with these serovars is considered the main source of infection. Methodology: In this study, 100 raw chicken meat samples were investigated for the presence of Salmonella spp., which were subsequently identified based on biochemical and serological tests as well as matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) profile. Furthermore, the isolated serovars were examined using multiplex polymerase chain reaction (PCR) for the presence of virulence genes suspected to have a role in infection. Results: S. Enteritidis was isolated from two samples (2%), while S. Typhimurium was isolated from three samples (3%) of chicken meat. Of the 17 examined virulence genes using multiplex PCR, the sitC, sopB, sifA, lpfC, spaN, sipB, invA, spiA, and msgA genes were detected in S. Enteritidis. However, the sitC, iroN, sopB, sifA, lpfC, spaN, sipB, invA, and tolC genes were successfully amplified in S. Typhimurium. Conclusions: The detection of S. Enteritidis and S. Typhimurium in meat, even at low incidence, has important implications. In addition, the data presented here is the first attempt to identify a wide range of virulence genes in Egyptian Salmonella isolates recovered from meat products. A strict public health and food safety regime is urgently needed in order to decrease the human health hazard risk associated with salmonellosis.

ABSTRACTGenes encoding ciprofloxacin resistance in enterococci in animals may be transferred to bacteria in the animal gut and to zoonotic bacteria where they could pose a human health hazard. The objective of this study was to characterize antimicrobial resistance in high-level ciprofloxacin-resistant (HLCR) Enterococcus faecalis and Enterococcus faecium isolated from retail chicken meat. A total of 345 enterococci (335 E. faecalis and 10 E. faecium) were isolated from 200 chicken meat samples. Of these, 85 E. faecalis isolates and 1 E. faecium isolate were confirmed as HLCR enterococci. All 86 HLCR enterococci displayed gyrA-parC point mutations consisting of S83I-S80I (94.2%, 81 isolates), S83F-S80I (2.3%, 2 isolates), S83Y-S80I (2.3%, 2 isolates), and S83Y-S80F (1.2%, 1 isolate). Sixty-one (72.9%) of the 86 HLCR enterococci showed multidrug resistance to three to six classes of antimicrobial agents. Multilocus sequence typing revealed that E. faecalis had 17 different sequence types (ST) and E. faecium had 1 different ST, with ST256 observed most often (44 isolates, 51.8%). Although these results cannot exclude the possibility that pathotypes of enterococci isolated from chicken might represent transmission to or from humans, the foodborne HLCR E. faecalis indicated that the food chain is a potential route of enterococcal infection in humans.

The presence of antibiotic residue in chicken and animal meats is a serious threat to human health due to its harmful effects. This study aimed at identifying the antibiotic resistance patterns of the isolates as well as antibiotic residues in chicken, cattle, buffalo and goat meats in different southern districts of Bangladesh. A total of 205 meat samples, including 70 chicken meat, 60 cattle meat, 50 buffalo meat and 25 goat meat were aseptically collected and analysed for the detection of antibiotic residues by thin layer chromatography and the isolates obtained from these samples were subjected to antibiogram study against 16 commonly used antibiotics. The isolates found in this study were Staphylococcus spp., Streptococcus spp., Escherichia coli, and Salmonella spp. and their prevalence were 37.5% (77/205), 22.1% (48/205), 29.7% (61/205), 8.7% (19/205), respectively. The isolates showed different degrees of sensitivity to the antibiotics used in the study. The most resistant phenotype was against cefradine, amoxicillin, penicillin, oxytetracycline, erythromycin, and enrofloxacin. 18.5% (38/205) meat samples were found to be positive for antibiotic residues and the highest prevalence was observed in chicken meat compared to other meat types. Overall, the findings of the study suggest that it is important to take controlling measures for the emergence of antibiotic resistance and also for ensuring healthy meats for human consumption.

Food borne salmonellosis is a major public health problem worldwide. This study aimed to detect the occurrence and antibiotics sensitivity of Salmonella species in grilled chicken meat sold at retail outlets in Erbil City, Kurdistan, Iraq. Two hundred and twenty-five (225) samples were aseptically collected from central and suburb retail outlets. For isolation of salmonellae, samples were cultured on selective media and tested for their susceptibility to common antibiotics by disk diffusion assay. The results revealed that the overall prevalence of Salmonella among grilled chicken meat samples was 7.1%. The isolates belonged to eight different serotypes of Salmonella. These include S. Typhimurium, S. Tennessee, S. Newport, S. Enteritidis, S. Anatum, S. Arizona, S. Muenchen, and S. Montevideo. The antibiotic resistance profile revealed a total resistance to Levofloxacin and total sensitivity to Cefotaxime, Amoxicillin, and Cefadroxil. This resistance among Salmonella may pose a public health hazard that requires effective precautions and response.

ABSTRACTThe aim of this study was to investigate the toxin gene profile and antimicrobial resistance of Staphylococcus aureus isolates from raw chicken in the People's Republic of China. In total, 289 S. aureus isolates were characterized by antimicrobial susceptibility testing, and genes encoding enterotoxins, exfoliative toxins, Panton-Valentine leukocidin, and toxic shock syndrome toxin were revealed by PCR. Overall, 46.0% of the isolates were positive for one or more toxin genes. A high proportion of toxin genes were pvl (26.6%), followed by sej (12.5%), sea (9.0%), seh (8.3%), seb (6.9%), sec (6.9%), sed (4.8%), sei (3.1%), and see (2.4%). None of the isolates harbored seg, tsst-1, or exfoliative toxin genes. In total, 29 toxin gene profiles were obtained, and pvl (10.7%) was the most frequent genotype, followed by sea (5.9%), seb (4.8%), and sej (4.2%). Furthermore, 99.7% of the strains were resistant to at least one of the tested antimicrobial agents, and 87.2% of them displayed multidrug resistance. Resistance was most frequently observed to trimethoprim-sulfamethoxazole and erythromycin (86.2% for each), followed by tetracycline (69.9%), amoxicillin–clavulanic acid (45.0%), and ampicillin (42.6%). None of the strains were resistant to vancomycin. This study indicates that S. aureus isolates from raw chicken harbored multiple toxin genes and exhibited multiple antimicrobial resistance, which represents a potential health hazard for consumers.

Food can be a carrier for pathogenic agents that can disease in consumers (foodborne disease). Chicken meat is one of the products from livestock which has a high consumption rate, because besides being easy to obtain, the growth of chickens is fast, and the price is also more affordable compared to large livestock types. Chicken meat is an excellent medium for microbial growth and makes it a perishable food ingredient. Foodborne illness is a disease caused by pathogenic microorganisms that contaminate food, such as Salmonella spp, Staphylococcus aureus, and Escherichia coli (E.coli). Salmonella spp infection can cause salmonellosis which irritates the digestive tract and many of them result in death. This study aims to assess the presence and number of pathogenic microorganisms Salmonella spp in broiler chicken sold in traditional and modern markets in Bandar Lampung. The research was conducted by purposive sampling of 30 chicken meat samples. Broiler chicken carcass samples were taken as whole and then stored in sterile plastic, labeled and put into a cool box filled with ice. The variables observed in this study were the presence and number of Salmonella bacteria. The data obtained were analyzed descriptively. The results of Salmonella spp examination on chicken meat samples in traditional markets in Bandar Lampung City showed a positive  in 1 (one) sample or 6.7%, while in modern markets Salmonella was not found. The presence of Salmonella in chicken meat is thought to be due to contamination from the water used during the process of slaughtering and preparing the carcass, contamination from the carcass slaughtering and selling environment which does not apply good sanitary hygiene and poor personal hygiene of the traders. The conclusion obtained is that the number of Salmonella spp in chicken meat in traditional markets is not in accordance with SNI 7388 of 2009 concerning the Maximum Limit of Microbial Contamination (BMCM) in fresh meat.

Development of a simple, rapid and specific assay for the simultaneous detection of Campylobacter spp. and Salmonella spp. based on duplex loop-mediated isothermal amplification (d-LAMP), combined with lateral-flow biosensor (LFB) is reported herein. LAMP amplicons of both pathogens were simultaneously amplified and specifically differentiated by LFB. The specificity of the d-LAMP-LFB was evaluated using a set of 68 target and 12 non-target strains, showing 100% inclusivity and exclusivity. The assay can simultaneously detect Campylobacter and Salmonella strains as low as 1 ng and 100 pg genomic DNA per reaction, respectively. The lowest inoculated detection limits for Campylobacter and Salmonella species in artificially contaminated chicken meat samples were 103 CFU and 1 CFU per 25 grams, respectively, after enrichment for 24 h. Furthermore, compared to culture-based methods using field chicken meat samples, the sensitivity, specificity and accuracy of d-LAMP- LFB were 95.6% (95% CI, 78.0%-99.8%), 71.4% (95% CI, 29.0%-96.3%) and 90.0% (95% CI, 73.4%-97.8%), respectively. The developed d-LAMP-LFB assay herein shows great potentials for the simultaneous detection of the Campylobacter and Salmonella spp. and poses a promising alternative approach for detection of both pathogens with applications in food products.

Background: Gastroenteritis caused by Salmonella spp. is mainly related to the consumption of undercooked chicken meat or raw poultry products. The objective of this study was to assess the occurrence of Salmonella spp. in chicken carcasses and giblets commercialized in Southern Chile (Valdivia city). Methodology: A total of 560 samples were collected from four supermarkets and one poultry products dealer, during two periods (autumn-winter and spring-summer periods), and analysed for Salmonella using standard bacteriological procedures. Results: Five out of 280 analyzed carcasses (1.8%) and one out of 280 (0.4%) chicken giblets were Salmonella positive. The isolation frequency of Salmonella spp. considering the total samples analyzed was 1.1%. Salmonella Enteritidis was the only serotype isolated. No significant differences (P > 0.05) in the isolation rates between the autumn-winter and spring-summer periods were found. Conclusion: Salmonella Enteritidis was isolated in low frequency from chicken carcasses and giblets commercialized in Southern Chile (Valdivia city); however, in spite of the low frequency of contaminated samples, this kind of food could be a potential vehicle of Salmonella infection to humans.

Foodborne pathogens are serious public healthproblems that greatly affect the cost of food production and healthcare while poultry are often associated with foodborne disease outbreaks. This study aimed at investigating the occurrence and distribution of bacterial pathogens associated with chicken meats sold around Bayero University, Kano old site. A total of twenty (20) meat samples comprised of 10 frozen and ten freshly slaughtered chicken were purchased from different selling outlets around the study area. The samples were processed using standard cultural and biochemical procedures. The results of the study showed the mean aerobic mesophilic bacterial count of 5.93 x 106 CFU/g and 3.12 x 106  CFU/g for frozen and freshly slaughtered chicken meat samples respectively. The coliform counts were 420.1 and 347.7 CFU/100g for frozen and freshly slaughtered chicken meat samples respectively. The distribution of different bacterial species revealed E. coli (26.0%), Klebsiella spp (4.0%), Salmonella spp (19.5%), Campylobacter spp. (14.6%) and Staphylococcus aureus (30%) in frozen chicken meat samples while freshly slaughtered chicken meat samples revealed E. coli (21.0%), Klebsiella spp (8.9%), Salmonella spp (30%), Campylobacter spp. (15.0%) and Staphylococcus aureus (24.0%). This showed that frozen chicken meats were more contaminated than freshly slaughtered chicken meats which might be associated with poor handling and storage conditions.

ABSTRACT Salmonella is an important foodborne pathogen that causes public health problems globally, and the increase of antimicrobial resistance in Salmonella has intensified the problem. Chicken meat is an important reservoir and disseminator of Salmonella to humans. This study aimed at estimating the burden of Salmonella carrying extended-spectrum β-lactamase (ESBL) and their antimicrobial resistance pattern in 113 domestic frozen chicken meat samples purchased from supershops available in five divisional megacities of Bangladesh. The study also focused on the determination of β-lactamase–, and plasmid-mediated quinolone resistance–encoding genes. All samples were analyzed for the presence of Salmonella using selective media and PCR assay. Antimicrobial susceptibility test was done by disk diffusion test, and ESBL screening was performed by double-disk synergy tests. Resistance genes were detected using multiplex PCR. Of samples, 65.5% were positive for Salmonella spp., and, of these, 58.1% isolates were ESBL producers. All the isolates were multidrug resistant (MDR): 40.5% were resistant to both three to five and six to eight antimicrobial classes; 17.6% were resistant to 9 to 11 classes, and 1.4% isolates to 12 to 15 classes. The highest rates of resistance were observed against oxytetracycline (100%), followed by trimethoprim-sulfamethoxazole (89.2%), tetracycline (86.5%), nalidixic acid (83.8%), amoxicillin (74.3%), and pefloxacin (70.3%). Notably, 48.6% of isolates demonstrated resistance to imipenem. One (1.4%) isolate was possibly extensively drug resistant. All the isolates were positive for the blaTEM gene, 2.7% were positive for blaCTX-M-1, and 20.3% for blaNDM-1. The prevalence of qnrA and qnrS genes was 4.1 and 6.8%, respectively. This study shows that ESBL-producing Salmonella are widespread in frozen chicken meat in Bangladesh, which puts greater responsibility on food processors and policy makers to ensure food safety.
