Is it okay to eat grapes with a slightly rotten stem

It is usually not recommended to consume grapes with slightly rotten stems. Rotting grape stems may be caused by fungal contamination, improper storage, or transportation damage, and the rotten area may produce harmful substances that spread to the flesh. When the grape stem rots, mold may have invaded the interior of the flesh through the stem duct, and even if the flesh is not visibly spoiled, there is still a risk of microbial contamination. Common molds such as Penicillium can produce toxins such as penicillin, which are difficult to completely destroy even when cooked at high temperatures. The flesh around the rotten area may have undergone changes such as softening texture and bitter taste, which may cause gastrointestinal discomfort after consumption. If the grape stem is only slightly withered and withered without mold spots, and the flesh is intact without damage, removing the stem and thoroughly cleaning can reduce the risk. However, children, pregnant women, and immunocompromised individuals should avoid consuming any fruits with signs of decay, as these groups are more sensitive to mycotoxins. When storing grapes, they should be kept dry and ventilated, and rotten fruits should be promptly removed to avoid cross contamination.

When purchasing grapes in daily life, you can observe whether the connection between the stem and the fruit stem is fresh and green, and gently pinch the fruit to confirm its hardness. Rinse with running water and soak in fruit and vegetable cleaner before consumption to remove surface pesticide residues and microorganisms. When fruits are slightly rotten, it is recommended to discard them whole to avoid health problems caused by small losses. It is safer to choose fresh fruits of the current season.
