ABSTRACT
The B. cereus group today consists of seven different species. One of them is Bacillus anthracis. Several of the species can cause food poisoning and will in most cases not be distinguished in routine food laboratories, apart from B. anthracis which is usually not haemolytic and is sensitive to penicillin. It has also been suggested that all these species are so closely related that they should be considered as the same species. In this overview the B. cereus group (apart from B. anthracis) will be handled mostly as the same species.
