Botulism is a rare but potentially fatal disorder. It is caused by a toxin, or poison, produced by the bacteria Clostridium botulinum.
Botulinum toxins are among the most powerful poisons known. There are three forms of botulism:
Botulism is caused by a toxin made by the Clostridium botulinum bacteria. Foodborne botulism in adults and children is acquired by eating improperly preserved or stored food that contains the toxin. Home canned food is a major source of foodborne botulism.
Infant botulism can be caused by eating honey, which may contain botulism spores. It can also be caused by eating food containing the toxin.
Wound botulism occurs when the bacteria enter a wound, grow, and produce the toxin. Black-tar heroin injections are a prime source of wound botulism.
