The white worms born in rice are the larvae of rice weevils. Rice weevils are non-toxic and can be eaten, but they will destroy the nutritional value of the rice. Rice weevils live on rice when the rice is still a seedling, and gradually move to the rice as it matures, so they are taken away with the rice during the harvesting process. Rice is sterilized and killed during processing, and adult rice weevils die and are sieved out during these processes, but the eggs laid on the rice cannot be completely eliminated. The hatching time of the eggs is usually 5 months, and during this time or at higher temperatures, white worms, known as rice weevil larvae, hatch. Rice weevils live their entire lives in rice and basically do not carry pathogenic bacteria, so these rice contaminated by white worms are still edible. Rice weevils feed on rice, and the bitten rice will not have residual toxins. Rice that has been eaten or spawned will float up in the rice panning process due to internal vacancies, and it is then necessary to discard these rice directly, and the white worms will die directly after the rice is steamed. If you mind, you can pick them out directly, but the remaining rice is non-toxic and edible. If you want to remove the white worms from the rice, you can spread the rice out in a cool, dry place to find the worms. Then freeze and store the remaining rice, the low temperature state usually will not continue to hatch white worms. In addition, you can take methods to keep dry to prevent the hatching of white worms, such as using wooden barrels for rice and keeping them dry. You can also try adding tea, pepper or volatile wine to the rice. The smell produced by these things can disperse white worms and reduce rice worming.
