Mondo Knows Facts

Reheated rice carries a spore risk

Cooked rice left warm can grow Bacillus cereus, which survives reheating Uncooked rice often carries spores of Bacillus cereus, which survive cooking. If cooked rice sits at room temperature, the spores germinate and the bacteria multiply, producing toxins that heat does not destroy. Cooling rice quickly and refrigerating it within an hour, then reheating it thoroughly once, limits the risk. It sits in Mondo's food collection, one of 200 facts that each trace back to the reference below.
