the best way to store cooked rice in the refrigerator and not leave it out for long periods, because rice may be exposed to the growth of some types of bacteria if it remains at room temperature.

This bacterium's spores can survive the cooking process. Once cooked rice is left at room temperature, these spores can multiply and produce toxins. Even reheating the rice may not eliminate these toxins, posing a risk of illness. Therefore, it is best to avoid consuming rice left out for extended periods, even if it appears and smells normal.

Uncooked rice may contain Bacillus cereus bacteria spores, which can survive after cooking.

To ensure safety, food guidelines recommend cooling cooked rice as quickly as possible, ideally within an hour. Avoid letting it cool slowly in the pot. Dividing large quantities into smaller, shallower containers speeds up cooling. Once cooled, refrigerate the rice. It is best to consume refrigerated rice within 24 hours.
