Which food is most associated with Bacillus cereus emetic illness when left at room temperature?

Bacillus cereus emetic illness comes from a preformed toxin that can form when cooked foods are kept at room temperature. The classic at-risk food is cooked rice left out, because starch-rich dishes provide conditions for the organism to grow and produce the toxin. That toxin is heat-stable, so reheating won’t destroy it. Other options like raw fish, cheese, or fresh vegetables aren’t as commonly linked to this emetic form. To prevent illness, cool cooked rice quickly and refrigerate promptly, avoiding holding it at room temperature.
