<p>We interviewed 57 party attendees. The median age was 15 years (interquartile range [IQR]: 8-30) and 61% were females. Forty-five (79%) reported symptoms including diarrhea (75%), abdominal pain (60%), and headache (59%). Of the 45 persons with illness, 41 (91%) sought medical care and 1 (2%) died. Consuming chibwantu was significantly associated with a higher rate of illness (73% vs. 25%, p=0.005). No association was observed for the consumption of other foods served during the party and sickness. Laboratory testing of the chibwantu specimens was negative.</p>
