Abstract
Background: An outbreak investigation was carried out to determine the cause and confirm the source of food poisoning in Deptsang village for implementing prevention and control measures. Methods: We conducted a retrospective cohort study for the outbreak investigation. Stool specimens were collected from cases to perform culture and antibiogram. The team also inspected the environment and hygiene practices in both the construction site and the entire community. The association between the exposure to carcass meat and their outcome of acute gastroenteritis was assessed by risk ratio. P<0.05 was considered statistically significant. Results: Fifty-five villagers consumed the carcass meat during lunch and dinner resulting in 33 cases. Multi-drug resistant Aeromonas hydrophila was isolated from stool specimens of cases, which were susceptible to chloramphenicol only. A risk ratio of 2.1 was found between those people who consumed the carcass meat and those who did not consume the carcass meat (P<0.001). Conclusions: The current outbreak of food poisoning was caused by the consumption of carcass meat contaminated with A. hydrophila. Provision of health education with emphasis on food hygiene is needed in remote areas to prevent such outbreaks in the future.
