Summary
Puffer fish poisoning, caused by tetrodotoxin, is rare but serious. 11 cases in NSW over 16 months highlight the need for health professional awareness and prompt management of this neurotoxic illness.
Area of Science:
- Toxicology
- Marine Biology
- Public Health
Background:
- Puffer fish poisoning is uncommon in Australia.
