According to the picture you provided, this insect is the larva of rice borer. Grain borer is a common stored-grain pest, which is common in grain stored for a long time or under improper storage conditions. Their larvae will grow in rice, noodles and other foods, and may lead to food deterioration and pollution.

If you find this kind of bug in the kitchen, I suggest you take immediate measures to clean the kitchen and discard the contaminated food. In order to avoid the recurrence of corn borer, some preventive measures can be taken, such as storing food in dry and sealed containers and keeping the kitchen clean.

It should be noted that although rice borer larvae may grow in food, they will not spread diseases themselves and have no direct harm to human body. If a large number of such insects are found, it is recommended to seek professional pest control services.
