Botulism is a serious, potentially fatal illness caused by a type of poison. The poison â known as botulinum toxin â is produced by a kind of bacteria. Botulinum toxin is the strongest poison known to science. Botulism is always considered a medical emergency. It can cause death by paralyzing the muscles people use to breathe. However, over the past 50 years, with better care, the death rate for people with botulism has dropped from 50 percent to eight percent.
Botulism is a serious illness that causes flaccid paralysis of muscles. It is caused by a neurotoxin, generically called botulinum toxin, produced by the bacterium Clostridium botulinum (and rarely by C. butyricum and C. baratii). The neurotoxin is produced by bacteria called Clostridium botulinum. 2  The neurotoxin paralyzes muscles and can be deadly. 3  There are three major types of botulism that differ in how they are acquired: food-borne, wound, and infant botulism. 4  Food-borne botulism is usually caused by eating contaminated home-canned foods.
