Improperly stored rice, particularly when cooked and left at room temperature, can lead to the growth of Bacillus cereus. This bacterium is known for its ability to form spores that can survive cooking. When rice is cooked and then not properly cooled or stored, these spores can germinate and produce toxins, which may result in foodborne illness.

Bacillus cereus is particularly associated with starchy foods like rice and pasta; it can multiply rapidly in these environments if they are not kept at the appropriate temperatures. The bacteria can cause two types of illness: one characterized by vomiting due to the emetic toxin (commonly associated with fried rice) and another causing diarrhea through enterotoxins.

Understanding the potential dangers related to Bacillus cereus highlights the importance of proper food storage practices to prevent bacterial growth and ensure food safety, especially with rice dishes that are often prepared in large batches and can be left out for extended periods.
