BACKGROUND
An outbreak of food poisoning was reported from a Military establishment on 29 May 2011 when 43 cases of food poisoning reported sick in a span of few hours.
METHODS
A retrospective-prospective study was conducted. Data regarding the onset of symptoms, presenting features and history of food items consumed was collected. A detailed inspection of the mess for hygiene and sanitary status, cooking and storage procedure, and rodent nuisance was also carried out.
RESULTS
A total of 53 cases of food poisoning occurred between 29 and 31 May 2011. All cases had symptoms of diarrohea followed by fever (96.2%), headache (84.9%), abdominal pain (50.1%), nausea and vomiting (49.1%) and bodyache (39.6%) respectively. Based on the Attributable Risk (AR = 46.67%) and Relative Risk (RR = 4.5, 95% CI = 1.22-16.54) Potato-bitter gourd vegetable served during dinner on 28 May 2011 was incriminated as the food item responsible for outbreak.
CONCLUSION
Symptomatology, incubation period and presence of rodent nuisance suggested contamination of Potato-bitter gourd vegetable with non-typhoidal Salmonella spp.
背景
2011年5月29日，一家军事机构报告了一起食物中毒事件，数小时内有43例食物中毒患者。
方法
开展了一项回顾性前瞻性研究。收集了有关症状发作、临床表现及所食用食物历史的数据。还对食堂的卫生和清洁状况、烹饪和储存程序以及鼠患进行了详细检查。
结果
2011年5月29日至31日期间共发生53例食物中毒。所有病例均有腹泻症状，随后分别出现发热（96.2%）、头痛（84.9%）、腹痛（50.1%）、恶心和呕吐（49.1%）以及身体疼痛（39.6%）。基于归因风险（AR = 46.67%）和相对风险（RR = 4.5，95% CI = 1.22 - 16.54），2011年5月28日晚餐时供应的土豆-苦瓜蔬菜被认定为导致此次疫情爆发的食物。
结论
症状学、潜伏期以及鼠患表明土豆-苦瓜蔬菜受到非伤寒沙门氏菌属污染。
