Can green beans still be eaten by black bugs

Green beans with black worms are generally not edible and may pose a risk of spoilage or insect infestation. Black worms are usually larvae of mung bean weevils, and their secretions and metabolites may contaminate beans, which may cause gastrointestinal discomfort after consumption. The larvae of mung bean weevils feed on beans and lay eggs and hatch inside the beans, leading to nutrient loss and mold growth in the beans. Green beans that are susceptible to insect infestation may develop mold, discoloration, or odor, and even high-temperature cooking may not completely eliminate insect eggs and residual metabolites. Green beans with slight insect infestation can be thoroughly picked, cleaned, or consumed, but their taste and nutritional value have significantly decreased. If mung beans have large areas of insect infestation, mold spots, or obvious odors, they must be discarded and disposed of. Moldy beans may produce harmful substances such as aflatoxins, which cannot be decomposed at high temperatures. Long term intake can increase the risk of liver damage. Improper storage of mung beans can easily breed pests. It is recommended to store them in a cool and dry place or freeze them to inhibit the hatching of insect eggs.

When storing mung beans in daily life, you can first expose them to sunlight to kill the insect eggs, then put them in a sealed container and place natural insect repellents such as Sichuan pepper and garlic. When purchasing, choose current year's new beans with full granules and no insect eyes, and regularly check the status of the stored beans. If you experience symptoms such as abdominal pain and diarrhea after accidentally eating insect infested mung beans, you should seek medical attention promptly to investigate the risk of food poisoning and avoid self induced vomiting or medication.
