The objective of this study was to identify the phylogenetic analysis and antibiotic resistance of Listeria monocytogenes contaminating chicken meat in Surabaya. 60 chicken meat samples were collected from supermarkets, mobile vendors, and traditional markets in Surabaya. A selective medium is used for isolation and identification of Listeria monocytogenes by chopping 25 grams of the chicken meat and to put it into the sterilized Erlenmeyer flasks. Some methods were used for the identification procedures, such as biochemical and morphological tests, antibiotic resistance test, PCR, and sequencing; also a phylogenetic analysis was conducted by a neighbor-joining analysis using Genetix Mac ver 8.0 with hlyA genes of Listeria monocytogenes recorded in GenBank, such as Lineage I (KC808543), Lineage II (AY229462, AY229346, AY229499, and AY229404), Lineage III (KJ504139, HQ686043, KJ504116, and DQ988349), and Lineage IV (EU840690, EF030606). The result shows that the prevalence of L. monocytogenes in Surabaya contaminating the chicken meat samples from the supermarkets was 10% (2/20), from the mobile vendors was 0/20 (0%), and from the traditional markets was 5% (1/20). It was seen from the band at 456 bp fragment. Furthermore, three isolates found in Surabaya were included in the new lineages which were resistant to old-generation antibiotics such as sulfamethonazole-trimetophrim (SXT) and amoxyllin sulbactam (MAS), but they were still sensitive to new-generation antibiotics such as cefotaxime (CTX) and meropenem (MEM).

The current research emphasis on the isolation and differentiation of Listeria monocytogenes from different food samples most frequently infected with Listeriosis outbreaks. Crude chicken meat, raw milk, pasteurized cheese, ice cream and raw fish are samples from the city of Bangalore. The selective medium mainly used for the isolation of Listeria is oxford agar. Using isolated L. monocytogenes from food samples, morphologic and biochemical identification was carried out. 2 samples (fresh milk and Ice cream) were positive out of 5 samples; 3 samples (raw chicken meat, raw fish, and pasteurized cheese) were negative. The results conferred during this study indicate the contamination of Ice- cream and Raw Milk samples with L. monocytogenes.

Contamination of Salmonella was assessed in duck and chicken meat collected from supermarkets, traditional markets, internet shopping malls, and wholesale markets in Jeonlado, South Korea, in 2013. Salmonella contamination was found in 51.3% of duck meat samples and 3.7% of chicken meat samples. Salmonella contamination of duck meat samples differed by meat type, i.e., 69.8% of samples of whole ducks and 33.9% of samples of duck pieces. Six serotypes were identified from 64 Salmonella isolates in duck meat: Salmonella Typhimurium (37.5%), Salmonella Enteritidis (21.8%), Salmonella Stanley (3.1%), Salmonella Regent (1.6%), Salmonella Winterthur (3.1%), and Salmonella Westhampton (1.6%). All isolates were resistant to one or more antibiotics. Resistance to sulfisoxazole was most common (93.8% of isolates), followed by resistance to nalidixic acid (59.4%), ceftazidime (26.6%), and ampicillin (26.6%). To our knowledge, this study is the first to report Salmonella contamination in duck meat from Korea. Duck meat should be considered an important source of foodborne pathogens.

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.

The prevalence of Salmonella was determined in chicken meat (n = 26), beef (n = 49), and pork (n = 56) collected from wholesale markets, retail stores, and traditional markets in Seoul, South Korea, in 2009. Antibiotic resistance was assessed, and the molecular subtypes of Salmonella isolates were ascertained using an automated repetitive sequence–based PCR (rep-PCR) system (DiversiLab). A total of 18 Salmonella strains were isolated from 17 of 131 samples: 16 strains from each of 16 samples and 2 strains from the same pork sample. The prevalence of Salmonella from the retail meats was 2.0% in beef, 8.9% in pork, and 42.3% in chicken meat. Among 10 different serotypes, Salmonella enterica Panama was recovered from a beef sample, and Salmonella London and Salmonella Montevideo were the predominant serotypes from pork and chicken meat, respectively. The highest antibiotic resistance observed was to erythromycin (100%) followed by streptomycin (22.2%) and tetracycline and chloramphenicol (16.7%). Of the 18 isolates, 5 (27.8%) were resistant to two or more antibiotics, and 1 isolate from chicken meat was resistant to eight antibiotics, including cephalosporins. Differentiation between all of the Salmonella isolates except between Salmonella Montevideo and Salmonella London was successfully performed with the automated rep-PCR system, indicating that it can be added to the toolbox for source tracking of foodborne pathogens associated with outbreaks.

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.

Introduction: Antimicrobial resistance is becoming a problem in public health. Zoonotic food-borne bacteria is infectious agent that can be transferred from animal to human through the food-producing animal we consume. Nowadays, antibiotic used for human and animal is not only to cure infection but also to aim animal’s growth promotion. It is known as non therapeutic antimicrobial agent (NTA) leading to antibiotic resistance. The third generation cephalosporins, cefotaxime, and also cefoxitin are included as important antibiotic for human. This study aims to identify the presence of cefotaxime-resistant Escherichia coli and cefoxitin-resistant Staphylococcus aureus isolated from chicken meat of both traditional and modern market in Surabaya.Methods: This is descriptive post test only experimental research. We used 8 samples of chicken meat from 4 different market using purposive sampling technique. We cultured Escherichia coli and Staphylococcus aureus from the chicken meat. Sensitivity test was done using Kirby-bauer disk-diffusion method.Results: All chicken meat sample bought from traditional market in Surabaya are contaminated by cefotaxime-sensitive Escherichia coli (n=4/4) while chicken meat sample bought from modern market are not contaminated by Escherichia coli (n=0/4). All chicken meat sample bought from traditional (n=4/4) are also contaminated by cefoxitin-sensitive Staphylococcus aureus. Half of chicken meat sample bought from modern market (n=2/4) are contaminated by cefoxitin-sensitive Staphylococcus aureus, while the other half (n=2/4) are contaminated by cefoxitin-resistant Staphylococcus aureus.Conclusion: Antibiotic resistance is found and all chicken meat samples have been highly contaminated with bacteria therefore food-processing should be done correctly.

Abstract Background Listeriosis is one of the globally distributed foodborne diseases with the highest fatality rate. Few studies were done on the occurrence of Listeria species from meat at abattoirs, butchers, and restaurants in Ethiopia, and there has been no study conducted at Ambo and Holeta town. The objectives of this study were to isolate and identify Listeria species, assess factors for contamination of meat, and antibiogram of Listeria monocytogenes along the meat chain in Ambo and Holeta towns, Central Ethiopia. Methods 450 meat samples were collected from abattoirs (n = 150), butchers (n = 150) and restaurants (n = 150) for isolation and identification of Listeria species using primary culture and biochemical tests. A questionnaire survey and observational checklist were made to assess the potential risk factors for the occurrence of Listeria species such as factors related to socio-demographic characteristics, knowledge on hygiene and practice of food handlers. Pearson’s Chi-square and logistic regression analyses were used to assess factors contributing for contamination of meat with Listeria species. Kirby Bauer disc diffusion technique was applied to determine the antimicrobial susceptibility profile of Listeria monocytogenes isolates. Results The overall occurrence of Listeria species in both Ambo and Holeta towns was 28.44% (128/450; 95% confidence interval [CI]: 24.32–32.86%). The occurrence of L. monocytogenes was 4.4% (20/450; 95% CI: 2.74–6.78%), L. ivanovii 2.2% (10/450; 95% CI: 1.07–4.04%), L. seeligeri 1.78% (8/450; 95% CI: 0.8–3.47%), L. welshimeri 3.77% (17/450; 95% CI: 2.22–5.98%), L. inoccua 6.22% (28/450; 95% CI: 4.17–8.87%) and L. grayi 10.22% (46/450; 95% CI: 7.58–13.39%). The probability of contamination of meat in butchers and restaurants by the Listeria species were comparatively higher in high altitude (Holeta) than medium altitudes (Ambo) [OR = 4.91; 95% CI: 2.65–9.07%; p < 0.001], in dry than wet season [OR = 8.78; 95% CI: 2.66–28.99%; p < 0.001] and in butchers and restaurant where the employees work ≥ 9 hours per day than those working ≤ 8 hours per day (OR = 3.57; 95% CI:1.74–7.36%; p < 0.001]. Of the 20 Listeria monocytogenes isolates, 16 (80%) were resistant to oxacillin; 14 (70%) were resistant to amikacin and nalidixic acid; 12 (60%) were resistant to chloramphenicol and 11 (55%) were resistant to tetracycline. The L. monocytogenes isolates were 95%, 90% and 85% susceptible to amoxicillin, vancomycin, and clindamycin, respectively. All (100%) Listeria monocytogenes isolates were resistant for two or more drugs. Nineteen (95%) L. monocytogenes isolates were multidrug-resistant. One isolate (5%) had developed resistance to 10 classes of antimicrobial drugs. Conclusions Listeria species are widespread in the study areas. The study towns, season and working hours per day are independent predictors of Listeria species isolation. Multidrug resistance among L. monocytogenes is common. Therefore, regular training for meat handlers, prudent use of drugs, and further serological and molecular studies on Listeria species are important.

The purpose of this study was to investigate the occurrence of Salmonella in raw chicken meat samples collected at the Romanian seaside and to evaluate the antimicrobial susceptibility of the isolates. In 2012, 317 chicken meat samples from slaughterhouses (n = 289) and retail markets (n = 28) were evaluated. Overall, 13.2% (42) of the samples contained Salmonella; 12.8% (37) and 17.8% (5) from the chicken carcasses at slaughterhouses and the fresh meat from retail markets, respectively. Eight serotypes of Salmonella enterica subsp. enterica were identified: Infantis (18 isolates), Bredeney (7), Virchow (6), Djugu (4), Grampian (4), Brandenburg (1), Derby (1), and Ruzizi (1). The isolates were resistant to tetracycline (66.6% of isolates), nalidixic acid (64.3%), sulfamethoxazole (64.3%), ciprofloxacin (61.9%), streptomycin (59.5%), trimethoprim (33.3%), ampicillin (9.5%), chloramphenicol (7.1%), and gentamicin (2.4%). No resistance was found to cefotaxime and ceftazidime. Thirty (71.4%) of the 42 tested isolates had multidrug resistance patterns to at least two antimicrobials. This survey highlighted a multidrug-resistant Salmonella contamination rate in raw chicken meat in this area of Romania, which can seriously threaten human health.

Introduction: Presence of Clostridioides difficile in stool of food birds and animals is a risk for contamination of their meats to become potential sources of human infection. The main virulence factors of C. difficile are its resistance to antibiotics, production of toxins and spores. As far as I know, this is the first study to evaluate C. difficile prevalence in chicken meats, its toxigenic activities and antibiotics sensitivity patterns in Al-Jouf, Saudi Arabia. Methodology: Totally, 250 raw chicken meat samples were examined. Standard microbiological and biochemical procedures were used for C. difficile isolation and identification. The suspected colonies were tested by L-proline and C. difficile test kits then confirmed by Vitek 2 compact system. Xpect C. difficile toxin A/B test was used to detect A/B toxins production. Antibiotics susceptibility patterns were detected by Epsilon tests. Results: C. difficile was isolated from 11/250 (4.40%) chicken meat samples; 5/65 (7.69%) legs, 3/65 (4.61%) thighs, 2/60 (3.33%) wings and 1/60 (1.67%) breasts (p = 0.4). All isolates were non-toxigenic. Although all isolates were vancomycin sensitive, some isolates were intermediate/resistant to metronidazole, tetracycline, clindamycin or moxifloxacin antibiotics with variable degrees. Conclusions: C. difficile might contaminate retail chicken meats. Although low level of contamination by non-toxigenic strains was detected, chicken meats should be investigated as C. difficile infection sources for humans especially elders, immune-compromised and long terms wide spectrum antibiotics-used persons. Decreased sensitivity of C. difficile to antibiotics is emerging.
