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 rare but serious illness caused by a toxin that affects the nervous system and can cause paralysis. The bacterium Clostridium botulinum, which is found commonly in nature, produces this toxin. There are several types of botulism, including foodborne botulism, which is caused by eating foods that contain the botulinum toxin. Botulism is a serious illness that should be treated as a medical emergency. Severe cases of botulism can lead to paralysis of the breathing muscles, respiratory or heart failure and death. If not diagnosed and treated, death from respiratory failure can occur within 1 to 10 days.
