Facts about Botulism
Botulism is a muscle-paralyzing disease caused by a toxin made by a bacterium called Clostridium botulinum.
There are three main kinds of botulism:
- Foodborne botulism occurs when a person ingests pre-formed toxin that leads to illness within a few hours to days. Foodborne botulism is a public health emergency because the contaminated food may still be available to other persons besides the patient.
- Infant botulism occurs in a small number of susceptible infants each year who harbor C. botulinum in their intestinal tract.
- Wound botulism occurs when wounds are infected with C. botulinum that secretes the toxin.
Botulism is not spread from one person to another. Foodborne botulism can occur in all age groups.
A supply of antitoxin against infant botulism is maintained by the California Department of Public Health’s Infant Botulism Treatment and Prevention Program, and a supply of antitoxin against other kinds of botulism is maintained by CDC. The antitoxin is most effective in reducing the severity of symptoms if administered early in the course of the disease. Most patients eventually recover after weeks to months of supportive care.
