Can the remaining portion of the fruit be eaten after it has rotted

When a portion of a fruit is rotten, the remaining portion is usually not recommended for consumption. Decay may be caused by fungal contamination, bacterial growth, or oxidative reactions, and even if visible spoilage areas are removed, microbial toxins may have spread to the uncorroded parts. After local decay of fruits, toxins such as penicillin produced by mold can penetrate into surrounding tissues, making it difficult to determine the extent of contamination with the naked eye. Common fruits that are prone to toxin production include soft fruits such as apples, pears, and peaches, whose mycelium may have spread to the deeper layers of the flesh. When bacterial decay occurs in berries such as grapes and strawberries, pathogenic microorganisms may spread through the juice and cause gastrointestinal discomfort after consumption. Some fruits with slight bumps or frostbite, if there are no mold spots and the flesh is normal, have a lower risk of consumption in the short term after removing the damaged area. Thick skinned fruits such as bananas and citrus fruits have a relatively low probability of internal contamination due to their outer skin protection, but it is necessary to ensure that the flesh does not have any abnormal discoloration or odor. For the elderly, children, and immunocompromised individuals, any rotten fruits should be avoided from consumption. When storing fruits, attention should be paid to ventilation and avoiding light, and spoiled fruits should be cleaned up in a timely manner to prevent cross contamination. Prioritize choosing fresh fruits of the season and purchase them in small quantities multiple times to reduce storage time. If symptoms such as abdominal pain and diarrhea occur after ingesting rotten fruits, it is recommended to supplement with diluted salt water in moderation. If the symptoms persist or worsen, seek medical attention promptly. Daily advice is to judge the freshness of fruits by observing changes in color and odor, in order to avoid food safety risks caused by conservation.
