Compact Dry Bacillus cereus X-BC | Nissui

Bacillus cereus is a gram-positive, aerobic, spore-forming bacterium which usually thrive in soil, vegetable, and various raw and processed food products. Bacillus spores can survice adverse condition and germinate if conditions improve, a trait which makes completely eliminating them difficult. Studies showed that when the bacterial population of bacillus cereus reached more than 10 cells/g toxins are produced, it can either be emetic or diarrhetic enterotoxin which attributed with acute attack of nausea and vomiting, or with abdominal pain and non-body diarrhea, respectively. with this Bacillus is considered as a release parameter for cooked meat and vegetables, boiled and fried rice, vanilla sauce, custards, soups, and raw vegetable sprout.
