The association of Bacillus cereus with cooked rice and rice dishes is well-documented and stems from the bacterium’s ability to form heat-resistant spores. When rice is cooked and then left at room temperature, these spores can survive the cooking process. If the rice is not promptly cooled and stored properly, the spores can germinate, leading to growth of the bacteria. These bacteria can produce toxins that can result in foodborne illness.

Bacillus cereus often causes two types of foodborne illness: one characterized by diarrhea and the other by nausea and vomiting, typically associated with reheated fried rice. This is particularly relevant for foods that have been cooked in large batches and then kept warm for serving, as the conditions can favor the growth of this pathogen.

In contrast, while Clostridium perfringens is associated with a variety of cooked meats and poultry, and Staphylococcus aureus is linked to a range of dairy products and cooked foods, they are less specifically tied to rice dishes. Scombroid is related to fish rather than rice. Therefore, Bacillus cereus is the appropriate choice when discussing bacterial pathogens specifically linked to cooked rice.
