Tetrodotoxin poisoning
Tetrodotoxin poisoning is most commonly due to eating the puffer fish (fugu), a Japanese delicacy, but>100 freshwater and saltwater species contain tetrodotoxin. Early symptoms include paresthesias in the face and extremities, followed by increased salivation, nausea, vomiting, diarrhea, and abdominal pain. Potentially fatal respiratory paralysis can also occur. Treatment is supportive care with attention to ventilatory assistance until the toxin is metabolized, which may take days. The toxin cannot be destroyed by cooking or freezing.
