Can you still eat a small piece of fruit that has rotted

A small piece of fruit that has rotted is usually not recommended for continued consumption, as even removing the rotten part may pose health risks. Decay may be caused by microbial contamination, oxidative reactions, or mechanical damage, with main risks including the spread of fungal toxins, the proliferation of pathogenic bacteria, and the loss of nutrients. When fruits partially rot, toxins produced by mold may penetrate through juice to seemingly intact parts. For example, penicillin secreted by Penicillium expansum is resistant to high temperatures and spreads quickly, and may still remain even after removing the decayed area. Some mycotoxins may cause damage to the liver and nervous system, and long-term intake may increase health risks. Rotting parts are also a breeding ground for bacteria, and pathogenic microorganisms such as Escherichia coli and Salmonella may cause acute gastroenteritis. In rare cases, if there is only mechanical damage caused by collision and no mold, the damaged part and surrounding tissue can be immediately removed before consumption. But it is necessary to ensure that the damaged fruit has not been stored for more than two hours, and that the fruit itself is resistant to storage, such as hard fruits like apples and pears. Tropical fruits such as mangoes and bananas are more prone to microbial growth due to their soft tissues, and this method of treatment is not recommended.

It is recommended to choose fruits with intact appearance and no scratches, and store them in refrigeration or ventilation according to their characteristics after purchase. If decay is found, it should be promptly discarded to avoid contaminating other fruits. Daily attention should be paid to observing the humidity and temperature of the storage environment. Special populations such as children, pregnant women, or immunocompromised individuals should strictly avoid consuming any rotten fruits to prevent the occurrence of foodborne diseases.
