Bacillus cereus is an aerobic bacteria, spores found in soil and the environment throughout the world. He usually found in low levels in raw foods, dried and processed.
A common and well recognized cause of food poisoning, Bacillus cereus produces two types of toxins: a type of diarrhea and vomiting type.
The type of food borne diarrheal disease is usually associated with meat, milk and vegetables. The onset of the disease is 8 to 16 hours and lasts 12 to 14 hours.
The type of vomit this food poisoning is due to rice, grains, cereals and other foods rich in starch. The beginning is quite fast (30 minutes to 6 hours) and usually lasts a day or so. This type is often associated with outbreaks due to boiled rice kept at ambient temperature.
This type of food borne disease is rarely fatal and cannot be transmitted from person to person.
Improper storage of food products is the problem. Spores of Bacillus cereus can survive boiling and food, e.g. rice is stored at room temperature, the spores can germinate on toxin-producing bacteria. Then the person eats rice contaminated with preformed toxin that causes the disease.
The type of toxin vomit is also resistant to heat, much like the enterotoxin that causes food poisoning Staphylococcus aureus and cooking will destroy the toxin.
To avoid food poisoning of b. cereus, the key is completely cooking food and if you don't eat it immediately, hold it to 140 ° F or refrigerate immediately. Don't let the fresh food slowly.
