Botulism is one of the deadliest diseases known to medicine, caused by a toxin so potent that a microscopic amount can lead to life-threatening paralysis. Yet this same toxin has been transformed into one of the most widely used medical and cosmetic treatments in the world.

In this episode, we explore the fascinating history, science, and ethical complexities of botulism. From deadly foodborne outbreaks and infant botulism to military bioweapons research and the development of Botox, we examine how a single bacterial toxin has shaped medicine, public health, and modern society.

Join us as we uncover the story of Clostridium botulinum, how it attacks the nervous system, how clinicians diagnose and treat botulism, and why this deadly poison continues to spark debates about the line between healing and harm.
