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\u201324 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.<\/jats:p>","DOI":"10.5365\/wpsar.2024.15.3.1168","type":"journal-article","created":{"date-parts":[[2024,10,3]],"date-time":"2024-10-03T02:18:26Z","timestamp":1727921906000},"page":"36-42","source":"Crossref","is-referenced-by-count":2,"title":["Large-scale salmonella outbreak associated with banh mi, Viet Nam, 2024"],"prefix":"10.5365","volume":"15","author":[{"name":"Institute of Public Health, Ministry of Health, Ho Chi Minh City, Viet Nam","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tinh Huu","family":"Ho","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phuong Hoai","family":"Hoang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Institute of Public Health, Ministry of Health, Ho Chi Minh City, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lam Vo Thi","family":"Ngoc","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Dong Nai Department of Health, Bien Hoa City, Dong Nai, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minh Nguyen","family":"Dinh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Dong Nai Food Safety Department, Bien Hoa City, Dong Nai, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong Do","family":"Thanh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Dong Nai Food Safety Department, Bien Hoa City, Dong Nai, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Viet Nguyen","family":"Dinh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Dong Nai Food Safety Department, Bien Hoa City, Dong Nai, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O Phan","family":"Van","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Long Khanh Regional General Hospital, Long Khanh City, Dong Nai, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phuong Nguyen Thi","family":"Lan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Long Khanh Regional General Hospital, Long Khanh City, Dong Nai, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thanh Nguyen","family":"Quoc","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Long Khanh Regional General Hospital, Long Khanh City, Dong Nai, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nhan Ho","family":"The","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Institute of Public Health, Ministry of Health, Ho Chi Minh City, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nhan Le Dinh","family":"Trong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Institute of Public Health, Ministry of Health, Ho Chi Minh City, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chinh Van","family":"Dang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Institute of Public Health, Ministry of Health, Ho Chi Minh City, Viet Nam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3383","published-online":{"date-parts":[[2024,9,30]]},"container-title":["Western Pacific Surveillance and Response Journal"],"original-title":[],"deposited":{"date-parts":[[2024,10,3]],"date-time":"2024-10-03T02:18:32Z","timestamp":1727921912000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.wpro.who.int\/ojs\/index.php\/wpsar\/article\/view\/1168"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,9,30]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2024,9,30]]},"published-print":{"date-parts":[[2024,9,30]]}},"URL":"https:\/\/doi.org\/10.5365\/wpsar.2024.15.3.1168","relation":{},"ISSN":["2094-7321","2094-7313"],"issn-type":[{"value":"2094-7321","type":"print"},{"value":"2094-7313","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,9,30]]}}}
