There is no specific statistical data on the probability of eating frogs with parasites, but what is certain is that frogs do carry parasites. Parasites carried by frogs include sparganum. The infection probability of this parasite in frogs, snakes and other animals is as high as 49%. Once infected by sparganum, it will drill around in the human body and even wander into the brain. Most drugs can't kill this parasite, so they can only be removed by surgery. Therefore, in order to reduce the risk of eating frogs infected with parasites, it is suggested to choose frogs purchased through formal channels and inspected and quarantined.
