The small white bugs in prunes are fruit fly larvae, which are not hazardous to human health and generally do not cause major effects. Fruit flies feed on the juice of fruits, and due to the special shape of prune fruits, fruit fly larvae usually hide in them and are not found. As fruit flies do not come into contact with all kinds of dirt and garbage, their bodies carry fewer pathogenic bacteria and viruses, and they themselves do not contain toxic or harmful substances to humans, so accidentally ingesting fruit fly larvae generally will not have an effect on the human body. Although fruit fly larvae are not harmful, they may cause visual discomfort. You can use salt water and baking soda to soak prunes thoroughly and eat them after the fruit flies have been soaked out. Fruit fly larvae do not cause significant effects on humans. Observe for abdominal pain, nausea, bloating, etc., but if there is any discomfort, seek medical attention immediately.
