What should I do if I buy rotten fruits

It is recommended to discard rotten fruits directly to avoid consuming the spoiled parts. Fruit decay may be caused by microbial contamination, mechanical damage, improper storage, and other reasons, which may lead to gastrointestinal discomfort or food poisoning after consumption. After fruit rots, fungal toxins and bacterial metabolites are produced, and even if the rotten part is removed, the remaining part may still have invisible contamination to the naked eye. Microbial contamination is the main cause of fruit rot. Fungi such as Penicillium and Aspergillus may produce toxins such as penicillin, and high-temperature cooking is difficult to completely destroy. Mechanical damage can cause skin damage, accelerate microbial growth and oxidation reactions, and cause flesh browning and softening. Improper storage, such as excessive temperature, humidity, or poor ventilation, can promote mold growth, and mixing immature and ripe fruits may also accelerate spoilage.

Some fruits that have been slightly damaged but have not rotted can be cut off and consumed as soon as possible, but it is necessary to ensure that the color and odor of the flesh are normal. Even if there are only local spots on moldy fruits, they should be discarded as a whole, as fungal hyphae may have spread throughout the entire fruit. Fermented and flavored fruits may contain alcohol and harmful bacteria, which can cause dizziness or diarrhea after consumption. When tropical fruits such as mangoes and bananas have black spots, it is necessary to distinguish between naturally ripe spots and mold spots. If it cannot be confirmed, it is recommended to discard them.

When purchasing fruits on a daily basis, it is recommended to choose fresh products with intact appearance and no damage, and to avoid hoarding by purchasing small quantities multiple times. Classify and store during storage. Perishable fruits such as strawberries and grapes should be refrigerated, while tropical fruits such as bananas and mangoes should be stored at room temperature and ventilated. Thoroughly clean the skin before consumption, cut open and consume as soon as possible. If symptoms such as abdominal pain and vomiting occur after ingesting rotten fruits, seek medical attention promptly and keep the remaining fruits for testing.
