Clostridium botulinum (bacteria causing botulism) is found in soil and untreated water. Food contaminated by the preformed toxin causes a severe form of disease that can result in respiratory failure and death. Botulism may also occur if the organism enters open wounds and produces toxins there.
Symptoms occur within hours to a day after consuming the contaminated food, and can include:
- Abdominal cramps
- Breathing difficulty leading to respiratory failure
- Difficulty swallowing and speaking
- Double vision
- Dry mouth
- Nausea, vomiting
- Administration of antitoxin
- Injection of intravenous fluids (supportive treatment)
- Ventilator support (occasionally)
