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.
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.
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).
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.
开展了一次疫情调查，以确定德普桑村食物中毒的原因并确认源头，从而实施防控措施。
我们针对此次疫情调查开展了一项回顾性队列研究。从病例中采集粪便样本进行培养和药敏试验。调查团队还检查了建筑工地和整个社区的环境及卫生习惯。通过风险比评估接触胴体肉与急性肠胃炎发病结果之间的关联。P<0.05被认为具有统计学意义。
55名村民在午餐和晚餐时食用了胴体肉，导致33人发病。从病例的粪便样本中分离出多重耐药嗜水气单胞菌，该菌仅对氯霉素敏感。食用胴体肉的人群与未食用胴体肉的人群之间的风险比为2.1（P<0.001）。
当前的食物中毒疫情是由食用被嗜水气单胞菌污染的胴体肉引起的。偏远地区需要开展以食品卫生为重点的健康教育，以预防未来此类疫情的发生。
