Botulism
Botulism is a rare but serious illness caused by a toxin produced by the bacteria Clostridium botulinum. Illness can occur through eating food contaminated with the toxin, infection of an open wound or (particularly in babies) ingestion of spores that form toxins in the intestine. The treatment for botulism is an anti-toxin medication that neutralizes the toxin.
