Abstract
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.
