Rice can be left overnight for a few days

Rice can generally be stored overnight for 1-2 days, and the actual storage time depends on factors such as storage temperature, sealing degree, and environmental humidity. Rice is prone to bacterial growth at room temperature, especially heat-resistant microorganisms such as Bacillus cereus, which may lead to food poisoning. Boiled rice should be refrigerated as soon as possible, with a temperature controlled below 4 ℃ to slow down bacterial growth. When refrigerating, it is necessary to seal it with plastic wrap or put it in a sealed container to avoid water loss and odor contamination. If the rice becomes sticky, sour, or discolored, it indicates that it has spoiled and cannot be continued to be consumed. If you need to extend the storage time, you can pack the rice separately and freeze it. It can be stored for about one month at -18 ℃. Frozen rice should be thoroughly heated to a center temperature above 70 ℃ before consumption, but repeated thawing can accelerate quality deterioration. It is recommended to use it as needed. People with gastrointestinal sensitivity, pregnant women, and infants should avoid consuming overnight rice to prevent gastrointestinal discomfort.

When storing rice in daily life, it is recommended to cook and eat it according to the amount consumed to reduce excess. If storage is required, spread out the rice and cool it quickly before refrigeration or freezing to avoid prolonged exposure to dangerous temperature zones. When reheating, ensure even heating and pair it with fresh dishes for better nutritional balance and safety.
