Those thrill seekers trekking across southern Africa may come across this amphibian on the menu in places like Namibia. But be warned: the African bullfrog contains a variety of substances toxic to humans. Locals say that young frogs who have not yet begun to mate are the most lethal because of a toxin they carry. But, even if you eat the wrong parts of a post-mating frog at any time of the year, you risk kidney failure.
