An оutbreаk оf fоod poisoning occurred in three kindergаrtens in Berlin, Germаny, on 3 December 2007 after an excursion during which food was served. We conducted a study among the kindergarten children and personnel who participated in the trip. The overall attack rate among the 155 participants was 30.3%. It was 31% among children and 17% among adults. The consumption of rice pudding was associated with disease. Among those who ate rice pudding, the attack rate was 36%, compared with 0% for non-eaters. Bacillus cereus was identified from one vomit sample. The clinical and epidemiological characteristics suggest that B. cereus emetic toxin was the causative agent, although it could not be proven in the single vomit isolate. Single-portion ready-to-eat rice pudding was recommended for subsequent excursions and no further cases of food poisoning occurred. How many children had food poisoning?
