Abstract

Objective: To investigate the cause of a foodborne outbreak that occurred in Dong Nai province, Viet Nam, in 2024, and implement control measures.

Methods: 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.

Results: 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. Salmonella spp. were identified in food samples and clinical specimens. The bakery halted production, and the outbreak ended after 1 week.

Discussion: 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.

2024 年越南发生与 banh mi 有关的大规模沙门氏菌疫情。
目的:调查 2024 年在越南同奈省爆发的食源性疾病的原因,并采取控制措施:调查 2024 年越南同奈省爆发的食源性疾病的原因,并实施控制措施:方法:开展初步调查以确认疫情,随后进行流行病学和环境调查,以找到可能的致病食品。对临床标本和食物样本进行检测,以确定病原体:结果:共记录了 547 例有症状的病例,其中 2 例病情严重,需要体外膜氧合和通气,1 例死亡。在 99 个受访病例中,平均潜伏时间为 9 小时(2-24 小时不等),主要症状为发烧、腹痛、腹泻和呕吐。所有患者都曾进食当地一家面包店的班米饭。在食物样本和临床样本中发现了沙门氏菌属。面包店停止了生产,疫情在一周后结束:讨论:所有患者都只接触过一种共同的食物,这为调查过程提供了便利。这起疫情提醒小型零售商和外卖店注意食品安全管理,以防止今后再发生类似疫情。所有食品处理人员都必须遵守食品卫生原则,尤其是在高温环境下,因为高温会促进细菌生长。
