If you eat moldy dragon fruit, it may cause abdominal pain, bloating, diarrhea, vomiting and other gastrointestinal discomforts, and even food poisoning in serious cases. So don't eat moldy dragon fruit and discard it in time. Even if the dragon fruit is only partially moldy, cut off the moldy part should not be eaten. Because the rest of the dragon fruit interior may also breed mold, but the naked eye can not be observed, and mold consumption of toxins produced by the human body will have adverse effects.
It is recommended to buy dragon fruits in moderation and pick fresh ones. If you can't eat them all, you can keep them in a cool place away from light, but avoid getting moldy for too long. Note that dragon fruit should not be placed in the refrigerator, so as not to cause dragon fruit frostbite, not only to destroy the nutrition, but also easy to deteriorate and rot.
