Bacillus cereus can give rise to two distinct forms of foodborne disease, the emetic and the diarrhoeal syndromes. The emetic syndrome is believed to be associated with an emetic toxin pre-formed in food. Cooked rice is the most common vehicle, and the symptoms are similar to those of Staphylococcus aureus intoxication. The diarrhoeal type is caused by an enterotoxin and the symptoms generally parallel those of the Clostridium perfringens food poisoning. The heat resistance of B. cereus spores and the non-fastidious nature of the organism facilitates its survival and/or growth in a wide variety of foods. This review describes analytical methods available for the isolation, identification, and enumeration of the organism, in addition to details about biological and immunological methods for toxin assay. Data are also presented concerning the incidence and epidemiology of B. cereus food poisoning around the world, and especially in Japan.
