Botulism is a rare but serious illness caused by a toxin produced by the bacterium Clostridium botulinum. This toxin can affect the nervous system, leading to muscle weakness, difficulty breathing, and even paralysis. It is often linked to improperly canned or preserved foods, where the bacteria can thrive in low-oxygen environments. There are different types of botulism, including foodborne, infant, and wound botulism. Infant botulism occurs when babies ingest spores of the bacteria, which then grow in their intestines. Prompt medical treatment is crucial, as botulism can be life-threatening if not addressed quickly.
