Abstract

About 300 of 450 people who attended a New Year's Eve dinner in Trail, British Columbia, suffered from diarrhoea and abdominal cramps. Heavy growth of an aerobic, gram-positive, spore-forming bacillus resembling Bacillus cereus was recovered from remnants of green bean salad. Incubation period, symptomatology, and duration of illness in this outbreak closely resembled those observed in food-poisoning incidents attributed to B. cereus in Europe and the United States, but differed from those reported in Quebec and the United Kingdom and attributed to fried rice. Some common limitations of this investigation are discussed. Environ 300 des 450 personnes qui avaient assistée un diner du Nouvel An à Trail en Colombie Britannique avaient souffert de diarrhée et de crampes abdominales. On découvrit dans les restes de la salade de haricots verts la présence massive de bacilles anaerobiques, gram-posisitifs et sporulants qui ressemblaient au Bacillus cereus. La période d'incubation, les symptômes et la durée de la maladie se rapprochaient beaucoup des données observées au cours d'empoisonnements alimentaires attribués au Bacillus cereus en Europe et aux Etats-Unis mais différaient des cas rapportés au Québec et en Grande-Bretagne que l'on attribuait au riz frit. L'article présente également les limites habituelles de ce type d'enquête.
