- A poisonous substance, especially one produced by a living organism. Toxins can be products or byproducts of ordinary metabolism, such as lactic acid, and they must be broken down or excreted before building up to dangerous levels.

Bacterial toxins can sometimes be neutralized with antitoxins. Compare antitoxin.
