We conducted a case-control study using face-to-face interviews using structured questionnaires. To identify additional cases, we reviewed all food transactions from October 4-7. A case was anyone having consumed food from the café during that period with symptoms of diarrhea, vomiting, and fever (&amp;gt;38°C). Controls also consumed food in same period without symptoms. Patient stool and café food samples were tested for coliform bacteria, Salmonella enteriditis, Staphylococcus aureus. We conducted log-binomial logistic regression using R to estimate association between food and disease.
