Bacillus cereus is a pathogen that produces toxins. Two types of illnesses can occur, one causes diarrhea, the other causes nausea and vomiting.
The diarrheal type can occur within 6-15 hours with watery diarrhea and cramps. The vomiting, or emetic, type can occur within 30 minutes to 6 hours. The illness is typically gone in 24 hours.
Drink lots of fluids and get rest. If symptoms worsen, see a doctor.
The best defense is controlling temperature of foods as B. cereus can multiply quickly at room temperature.
