“Touching a toad will give you warts”

The idea that touching a toad will result in a crop of warts is a persistent old wives' tale, likely stemming from the visual similarity between the bumpy skin of a toad and the appearance of human warts. For centuries, people observed these amphibians with their textured backs and perhaps, after handling one, later developed a wart, leading to a false association. This misconception has been passed down through generations, making many wary of these harmless garden inhabitants.

The scientific truth, however, completely debunks this claim. Warts are caused by the human papillomavirus (HPV), a virus that infects human skin cells and causes them to grow rapidly. These viruses are specific to humans and cannot be transmitted from amphibians to people. The bumps on a toad's skin are actually glands, primarily parotoid glands located behind their eyes, which secrete a milky, sometimes toxic (Review) substance as a defense mechanism against predators. These secretions are not infectious in the way a virus is, and they certainly do not carry HPV.

People commonly believe this myth due to the superficial resemblance between a toad's glandular bumps and a human wart. Without an understanding of virology or amphibian biology, it's easy to jump to conclusions based on appearance. Additionally, the myth plays into a general human tendency to attribute unpleasant conditions to things perceived as "gross" or "unclean," a category into which toads, with their often slimy appearance, unfortunately fall for some. Rest assured, you can safely observe toads without fear of developing warts; your only concern might be washing your hands afterward to remove any natural secretions.
