Toxins

Toxins are substances created by plants and animals that are poisonous to humans. Toxins also include medications that are helpful in small doses, but poisonous when used in large amounts.

Most toxins that cause problems in humans are released by germs such as bacteria. For example, cholera is due to a bacterial toxin.

Other toxins that cause problems include metals, such as lead, and organic chemicals in the environment.
