Introduction
The long hairs on the rambutan are an indication of extensive mold growth. During their growth, molds secrete toxins such as aflatoxins, which are difficult to completely eliminate even after high-temperature treatment. Consuming rambutans contaminated by mold allows these toxins to enter the human body, potentially damaging organs such as the liver and kidneys, and causing food poisoning symptoms including nausea, vomiting, and abdominal pain, thus seriously endangering health.

    The hairy growth on rambutan is not edible, as it indicates mold contamination, which poses a health risk. Detailed analysis is as follows:

    The hair-like growth on rambutan is a sign of extensive mold proliferation. During its growth, mold can secrete toxins such as aflatoxins, which are difficult to completely eliminate even after high-temperature treatment. Consuming rambutan contaminated with mold allows these toxins to enter the human body, potentially damaging organs such as the liver and kidneys, and causing food poisoning symptoms like nausea, vomiting, and abdominal pain, seriously endangering health.

    Additionally, the presence of hair-like growth indicates the fruit has severely spoiled. Its internal nutrients have been broken down and destroyed by mold, and its taste and flavor have been completely lost. Not only does it no longer provide nutritional value, but spoilage may also generate other harmful microorganisms, further increasing the likelihood of illness after consumption.

    When storing rambutan in daily life, it should be kept in a cool, dry place and inspected regularly. If signs of spoilage such as hair-like growth, discoloration, or an unusual odor are detected, discard the fruit immediately. Do not risk consumption out of reluctance to waste it, in order to avoid illness caused by ingestion of contaminated food.
