Generally speaking, rice infested with insects is not recommended for consumption. The detailed explanation is as follows:

After rice becomes infested with insects, insect feces, shed skins, and dead insect bodies will remain among the rice grains. These substances not only contaminate the rice but may also carry microorganisms such as bacteria and fungi. Even after washing and steaming, it is difficult to completely remove these contaminants, increasing the risk of gastrointestinal discomfort, such as abdominal pain and diarrhea after consumption. Furthermore, rice that has been infested often indicates the rice has been stored for a long time or in a humid environment, causing partial loss of nutrients. The insects feeding on the rice damage the grain structure, resulting in a decline in texture, losing its original aroma and plumpness. Additionally, some insects may lay eggs in the rice, which are difficult to completely remove with the naked eye, posing potential health risks if consumed.

When rice infestation is detected, it should be promptly separated from other foods to prevent the insects from spreading to other food items. When storing rice, choose a dry, well-ventilated, and sealed container. Placing a few cloves of garlic or some dried prickly ash in the container may help prevent insect infestation. If the rice is heavily infested or shows signs of mold, it should be discarded immediately without hesitation. Even in cases of minor infestation, it is not advisable to consume the rice with侥幸心理 (a侥幸 attitude), as choosing fresh, insect-free rice is essential for food safety.
