Final answer:
Bacillus cereus intoxication is most commonly associated with fried rice, as the bacterium can survive cooking and produce toxins if the rice is left at room temperature.
Step-by-step explanation:
Bacillus cereus intoxication is more likely to occur following the consumption of foods that have been left at room temperature for an extended period. Specifically, fried rice is commonly associated with B. cereus food poisoning. This is due to the fact that the bacterium is a spore-forming organism that can survive cooking temperatures. If the cooked rice is then left at room temperature, the spores can germinate and produce toxins, leading to foodborne illness. Symptoms typically include nausea, vomiting, and diarrhoea and can appear within hours of consumption.
