To investigate the cause of a foodborne outbreak that occurred in Dong Nai province, Viet Nam, in 2024, and implement control measures.
An initial investigation was conducted to confirm the outbreak, which was followed by epidemiological and environmental investigations to find the plausible causative food item. Clinical specimens and food samples were tested to identify the pathogen.
A total of 547 symptomatic cases were recorded, of whom two were in severe condition requiring extracorporeal membrane oxygenation and ventilation, one of whom died. Among 99 interviewed cases, the mean incubation time was 9 hours (range 2-24 hours), with the main symptoms being fever, abdominal pain, diarrhoea and vomiting. All patients had eaten banh mi from a local bakery. spp. were identified in food samples and clinical specimens. The bakery halted production, and the outbreak ended after 1 week.
All the patients were exposed to only one food in common, which facilitated the investigation process. This outbreak is a reminder to small retailers and take-away shops of the importance of food safety management in preventing similar future outbreaks. All food handlers must comply with food hygiene principles, especially in hot temperatures, which boosts bacterial growth.
调查 2024 年越南同奈省一起食源性疾病暴发的原因，并实施控制措施。
开展初步调查以确认暴发，随后进行流行病学和环境卫生调查以确定可能的致病食物。采集临床标本和食物样本进行检测以鉴定病原体。
共记录到 547 例有症状病例，其中 2 例病情严重需要体外膜肺氧合和通气，其中 1 例死亡。在 99 例接受访谈的病例中，平均潜伏期为 9 小时（范围 2-24 小时），主要症状为发热、腹痛、腹泻和呕吐。所有患者均食用过当地面包店的面包。在食物样本和临床标本中均鉴定出 spp.。面包店停止生产，1 周后疫情结束。
所有患者均暴露于唯一的共同食物，这有助于调查过程。此次暴发提醒小型零售商和外卖店注意食品安全管理在预防类似未来暴发中的重要性。所有食品从业人员必须遵守食品卫生原则，尤其是在高温下，这会促进细菌生长。
