It is recommended that you should preferably not eat the skin and guts of frogs. Because parasites are most abundant in these two places. Only the ones that are cooked for a long time are free of parasites.

You can burn them in the microwave to ensure 100% killing of any parasites.

Other parasites that are hard to kill are the Mannheimia tapeworm, which won't die if you cook it. But not all frogs have that worm.

Beginning in Beijing in 2006, bullfrogs were "banned" for carrying a large number of parasites and germs, and frogs are mostly infected with tapeworms and larvae, and now more and more people are eating frogs, and cases of tapeworms and larvae have been found in Fujian and other places!
