Title: Extended-Spectrum -Lactamase-Producing Antibiotic-Resistant Escherichia coli and Klebsiella pneumoniae Prevalence and Characterization in Ready-to-Eat Street Foods
Abstract: Ready-to-eat (RTE) street foods, which are prepared with less structured food safety guidelines in small and roadside outlets, are posing food safety challenges as urban populations around the world rise due to rapid migration from rural areas. Due to its epidemiological significance, the increased prevalence of extended-spectrum-lactamase (ESBL) producing bacteria in street foods poses a serious risk to human health. Due to their connection to antibiotic resistance, Escherichia coli and Klebsiella pneumoniae have emerged as significant and hazardous foodborne pathogens worldwide. The goal of the current study was to evaluate the potential threat posed by antibiotic-resistant E. coli and K. pneumoniae contamination of RTE street foods as well as to evaluate the microbiological quality of food in a typical developing and expanding urban suburb of India where RTE street foods are quickly establishing with potential public health implications. 100 RTE food samples in total were gathered, of which 22.88% contained E. coli and 27.12% contained K. pneumoniae. K. pneumoniae and ESBL-producing E. coli were both prevalent (25.42%), and they were mainly found in chutneys, salads, paani puris, and chicken. With 86.44% of the isolates having a MAR index above 0.22, antimicrobial resistance was found to exist against cefepime (72.9%), imipenem (55.9%), cefotaxime (52.5%), and meropenem (16.9%). The most prevalent gene for -lactamases was blaTEM (40.68%), followed by blaCTX (32.20%) and blaSHV (10.17%). In 20.34% of the isolates, the blaNDM gene was found. This study showed that contaminated RTE street foods put consumers’ health at risk and that there is a high risk of spreading multi-drug-resistant bacteria as pathogens or as normal inhabitants of the human gut from person to person through food, creating difficulties for subsequent therapeutic treatments.
