Warts are caused by the human papillomavirus (HPV), a virus that infects the outer layer of human skin. Toads, on the other hand, do not carry HPV or any pathogen capable of producing warts in humans. This makes it biologically impossible for handling a toad to result in wart formation, regardless of how bumpy or wart-like the animal's skin may appear.

The persistent myth likely stems from the toad's skin texture, which features raised bumps and glands that visually resemble warts. These bumps are actually specialized glands, most notably the parotoid glands located behind the eyes, which secrete a milky toxin used for defense against predators. While this secretion can cause skin irritation, mild burning, or an allergic reaction in some people, it has no connection to viral wart development. Handling toads without washing hands afterward could theoretically introduce bacteria or irritants to the skin, but this is unrelated to the wart-causing virus.

Scientific consensus is unambiguous on this point: warts spread through direct or indirect contact with HPV, typically via skin-to-skin contact, shared surfaces, or damaged skin such as small cuts. Since toads cannot harbor or transmit this virus, no legitimate mechanism exists for them to cause warts. This claim represents a classic case of correlation being mistaken for causation, where a physical resemblance between toad skin and human warts created a folk belief that has persisted despite lacking any scientific basis.
