•Food and waterborne outbreak is a neglected public health problem in India.•A retrospective cohort study was conducted with a line list of one hundred thirty (130) cases.•Epidemiological investigation and laboratory investigation were done. Data were collected from hospital case report form as well as interviewed affected cases.•A case of acute diarrhoeal disease was reported among the people in the village with abdominal pain, vomiting and or diarrhea from 31st December 2022 to 3rd January 2023.•Out of a total 130 recorded cases, 33 stool samples were collected and were positive for Enteroaggregative Escherichia coli, Shigella flexneri 3a and shigella sonnei.•Quick identification of causative pathogens and their antimicrobial resistance pattern helped correct antibiotic prescription and quick recovery without any death. Food and waterborne outbreaks are a neglected public health problem in India. However, it is important to identify the source of infection and the causative pathogen to curb the outbreak quickly and minimize mortality and morbidity. A retrospective descriptive study was conducted with a line list of 130 diarrheal cases. Epidemiological investigation and laboratory investigation were done. Data were collected from hospital case report forms as well as interviewed affected cases. A case of acute diarrheal disease was reported among the people in the village with abdominal pain, vomiting, and diarrhea from 31st December 2022 to 3rd January 2023. Out of a total of 130 recorded cases, 33 stool samples were collected and were positive for Enteroaggregative Escherichia coli, Shigella flexneri 3a, and Shigella sonnei by cultural and molecular tests. The presumptive fecal pollution indicator assay indicated high coliform counts in the water samples (most probable number MPN-05) and the presence of Escherichia coli. The identified pathogens showed susceptibility to gentamicin and meropenem. People who used public drinking water were found to be infected with acute diarrheal disease (ADD). Quick identification of the causative pathogens and their antimicrobial resistance pattern helped correct antibiotic prescriptions and quick recovery without any deaths. Thus, a timely implementation of food and waterborne outbreak investigation is crucial to saving lives and preventing the spread of infection.
