Be able to explain how Bacillus cereus contributes to gastroenteritis. The species Bacillus cereus belongs to the so-called B. cereus group, which includes Gram-positive, aerobic or facultative, sporulating, rods that are almost ubiquitous in the natural environment. The first type of toxin is released in the small intestine after the bacteria are ingested, and causes diarrhea, cramps and occasionally nausea but rarely vomiting. Die vollständige Vermeidung der Kontamination von Lebensmitteln ist aufgrund der Überdauerungsfähigkeit der Sporen schwierig. Bacillus cereus can cause food poisoning, and it is able to survive on the rice even when it’s cooked.
