Fried rice is typically associated with diarrhea caused by which of the following microorganisms?

Fried rice is commonly associated with diarrhea caused by Bacillus cereus. This bacterium is known for its ability to form spores that can survive cooking and can be found in improperly stored fried rice. When cooked rice is kept warm for an extended period, the spores can germinate, and the bacteria can multiply. The toxins produced by B. cereus can lead to gastrointestinal symptoms, including nausea, vomiting, and diarrhea, typically within a few hours after consumption.

In the context of foodborne illnesses, B. cereus is classified into two types of toxin-mediated illnesses: the emetic syndrome, which is often linked to fried rice and results in vomiting, and the diarrheal syndrome, which can occur from consuming contaminated foods. Because fried rice is often prepared in large batches and kept warm, it becomes a suitable medium for the growth of Bacillus cereus, making it a common culprit in cases of gastroenteritis arising from contaminated rice dishes.
