Worms in prunes are generally fruit fly larvae rather than parasites, and therefore do not cause parasites to develop in the stomach when consumed. The bugs in prunes are not parasites, but are actually fruit fly larvae. Fruit flies are insects that live around decaying plants and fruits. They are harmless to humans and do not cause significant effects even after consumption, and they are broken down by digestive fluids such as gastric juices, and do not form parasites in the stomach. In order to avoid eating fruit flies, you can soak prunes in salt water for 10 to 20 minutes before consumption, and carefully wash them to remove as many larvae and eggs as possible. If you feel sick after eating, you should stop eating, and if necessary, you need to consult a doctor in time to standardize the diagnosis and treatment.
