Is it true that cooked rice left at room temperature allows Bacillus cereus spores to grow and cause food poisoning?

Yes. Multiple sources state that Bacillus cereus spores survive cooking of rice and can germinate and grow when cooked rice is left at room temperature, producing toxins that cause food poisoning. A microbiology reference and a study of boiled rice directly describe this mechanism, while other studies and clinical sources corroborate the link between improperly stored cooked rice and B. cereus illness.
