<p>There were 45 suspected cases (1fatal) and 1 confirmed case. Twenty-seven (60%) were males; median age was 27 (IQR 12-45) years. Case-patients presented with abdominal pain (96%), vomiting (60%), and non-bloody diarrhoea (57%). Compared to unexposed cohort members, persons who ate (RR=4.7, 95%CI: 1.8-12.6) or ate and prepared the meat (RR=4.9, 95%CI: 1.3-13.5) were at increased risk. Compared to those eating only boiled meat, those who ate only roasted meat (RR=2.7, 95%CI: 1.1-6.2) or fried and roasted meat (RR=2.8, 95%CI:1.2-6.7) were at increased risk. Twenty-five (89%) case-patients who provided information on the source of meat purchased meat from Butcher A. Interviews revealed that Butcher A obtained meat of a cow that died suddenly from the neighbouring district of Kazo and sold it in the community below the normal price.</p>
