Rice that is not fully heated is generally not recommended for direct consumption as it may pose health risks. Underheated rice may contain pathogenic microorganisms or cause digestive discomfort, and in special cases, it should be judged based on storage conditions and individual differences. When rice is not thoroughly heated, residual heat-resistant bacteria such as Bacillus cereus may continue to reproduce and produce toxins. These types of bacteria are prone to breed in rice stored at room temperature, and may not be completely inactivated even with secondary heating. After consumption, there may be gastrointestinal discomfort symptoms such as abdominal pain and diarrhea, and people with lower immunity have a higher risk. If the rice is refrigerated for a short period of time and there are no signs of spoilage such as odor or stickiness before heating, some people may not show obvious reactions, but there are still potential hazards. If overnight rice is stored at room temperature for more than two hours, the probability of microbial contamination significantly increases. When the temperature is high in summer or the moisture content of rice is high, the bacterial growth rate is faster. Special populations such as infants, pregnant women, etc. should avoid consuming undercooked rice. If the general population experiences symptoms such as vomiting and fever after accidentally consuming it, they should seek medical attention in a timely manner. For rice stored with the insulation function of an electric rice cooker, continuous temperature above 60 ℃ can inhibit bacterial growth, but it is still recommended to reheat it to the center temperature of 100 ℃ after more than four hours.

When handling leftover rice in daily life, it should be cooled as soon as possible and sealed for refrigeration. When reheating, ensure that the rice is evenly heated until it is steaming. Pairing fresh vegetables with high-quality protein foods can reduce digestive burden, and if gastrointestinal discomfort occurs, an appropriate amount of electrolyte solution can be supplemented. It is recommended to make careful judgments based on the storage time and condition of rice, and prioritize choosing a freshly cooked and eaten diet to ensure food safety.
