Are most species of frogs harmless?
A vast majority of frogs and toads have poison glands in their skin. Only a handful or two of them are deadly poisonous. But those that are dangerously poisonous have poisons that are among the most potent found in nature. No frog can inject its poison into anybody. The poison is released when a frog is harmed and may enter a predator’s body through the mucous membranes inside the mouth. After handling a frog, it is best to wash one’s hands with soap and water. Any poision that gets into the eyes can cause redness, swelling and general discomfort, even pain, until the effects wear off. It is one reason that people who eat frogs will discard the skin before cooking. Even toads are edible if the skin is removed before cooking.
