Abstract BackgroundThe prevalence of antimicrobial-resistant pathogens, including foodborne antibiotic-resistant bacteria, is ever increasing. An increase in antimicrobial resistance results in treatment failure and outbreaks. Mass food serving institutions are at a high risk of outbreaks due to the probability of mass infection.ObjectiveThis study aims to determine the contamination of food handlers with antibiotic-resistant bacteria and its associated factors at Debre Tabor University cafeteria.MethodsA laboratory-based cross-sectional study was conducted by following standard microbiological methods to isolate and identify foodborne bacteria from the hands of food handlers. The Kirby-Bauer disc diffusion method was used for perform the resistance profiles of the foodborne bacteria that were identified from the hands of the food in March 2020. Thirty samples each from hand and food utensil swabs were collected. Besides, work experience, drug use characteristics, and educational status of the food handler’s data were collected by using an observational checklist and interview questions. Descriptive statistics, correlation, and linear regressions were used to analyze the data.ResultsThe result shows the contamination of food handlers with varying pathogenic microbial organisms. The food handlers were mostly contaminated with multiple antibiotics-resistance (MAR) of Escherichia coli 43% (95% CI: 41.2%, 46.9%), Salmonella 36.7% (95% CI:33.2%, 38.7%), and Shigella 20% (95% CI: 19.2%, 26.9%). The study identifies poor personnel hygiene, lack of food safety training, and lack of sufficient food safety knowledge of the food handlers.ConclusionsThe contamination of food handlers with antimicrobial-resistant microbes at the university cafeteria could indicate the likelihood of the occurrence of foodborne outbreaks. Hence, continuous awareness creation and strict supervision were preventing the contamination of the food and related consequences.

In recent years, antibiotic-resistant bacteria with an impact on human health, such as extended spectrum β-lactamase (ESBL)-containing Enterobacteriaceae, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE), have become more common in food. This is due to the use of antibiotics in animal husbandry, which leads to the promotion of antibiotic resistance and thus also makes food a source of such resistant bacteria. Most studies dealing with this issue usually focus on the animals or processed food products to examine the antibiotic resistant bacteria. This study investigated the intestine as another main habitat besides the skin for multiresistant bacteria. For this purpose, faeces samples were taken directly from the intestines of swine (n = 71) and broiler (n = 100) during the slaughter process and analysed. All samples were from animals fed in Austria and slaughtered in Austrian slaughterhouses for food production. The samples were examined for the presence of ESBL-producing Enterobacteriaceae, MRSA, MRCoNS and VRE. The resistance genes of the isolated bacteria were detected and sequenced by PCR. Phenotypic ESBL-producing Escherichia coli could be isolated in 10% of broiler casings (10 out of 100) and 43.6% of swine casings (31 out of 71). In line with previous studies, the results of this study showed that CTX-M-1 was the dominant ESBL produced by E. coli from swine (n = 25, 83.3%) and SHV-12 from broilers (n = 13, 81.3%). Overall, the frequency of positive samples with multidrug-resistant bacteria was lower than in most comparable studies focusing on meat products.

As the global urban populations increase with rapid migration from rural areas, ready-to-eat (RTE) street foods are posing food safety challenges where street foods are prepared with less structured food safety guidelines in small and roadside outlets. The increased presence of extended-spectrum-β-lactamase (ESBL) producing bacteria in street foods is a significant risk for human health because of its epidemiological significance. Escherichia coli and Klebsiella pneumoniae have become important and dangerous foodborne pathogens globally for their relevance to antibiotic resistance. The present study was undertaken to evaluate the potential burden of antibiotic-resistant E. coli and K. pneumoniae contaminating RTE street foods and to assess the microbiological quality of foods in a typical emerging and growing urban suburb of India where RTE street foods are rapidly establishing with public health implications. A total of 100 RTE food samples were collected of which, 22.88% were E. coli and 27.12% K. pneumoniae. The prevalence of ESBL-producing E. coli and K. pneumoniae was 25.42%, isolated mostly from chutneys, salads, paani puri, and chicken. Antimicrobial resistance was observed towards cefepime (72.9%), imipenem (55.9%), cefotaxime (52.5%), and meropenem (16.9%) with 86.44% of the isolates with MAR index above 0.22. Among β-lactamase encoding genes, blaTEM (40.68%) was the most prevalent followed by blaCTX (32.20%) and blaSHV (10.17%). blaNDM gene was detected in 20.34% of the isolates. This study indicated that contaminated RTE street foods present health risks to consumers and there is a high potential of transferring multi-drug-resistant bacteria from foods to humans and from person to person as pathogens or as commensal residents of the human gut leading to challenges for subsequent therapeutic treatments.
