B. cereus is widely distributed in the environment, namely soil, where spores persist under adverse conditions. Terminal (leaf) node. Dried herbs and spices used in food preparation can be an important source of Bacillus cereus and this has often been cited as a reason for a relatively high incidence of Bacillus cereus food poisoning in Hungary, where between 1960 and 1968 it was the third most common cause of food poisoning accounting for 15.2% of persons affected. 2002) Coorevits et al.

Bacillus cereus A ubiquitous, aerobic spore-forming, gram-positive non-anthrax bacillus. As you can see, Bacillus cereus is very closely related to Bacillus anthracis (as mentioned earlier, Bacillus anthracis is more commonly known as anthrax) and Bacillus thuringiensis. Bacillus cereus and other Bacillus spp. Bacillus cereus. B. cereus is widely distributed in the environment, namely soil, where spores persist under adverse conditions. Common names include "anthrax" and "anthrax bacterium" (16). From 1998 to 2008, 1229 foodborne outbreaks caused by Bacillus cereus, Clostridium perfringens, and Staphylococcus aureus were reported in the United States; 39% were reported with a confirmed etiology.
