Which toxin is produced by a puffer fish?

• A. Staphylococcus Aureus
• B. Tetrodotoxin
• C. Thermistors
• D. Sulfiting Agents

Answer: (B)

Tetrodotoxin is the toxin produced by puffer fish. It is an extremely potent neurotoxin that works by blocking voltage-gated sodium channels in nerve and heart muscle. When these channels are blocked, nerve impulses and muscle contractions can’t be generated, leading to numbness around the mouth, tingling, dizziness, weakness, and, in severe cases, paralysis and respiratory failure. The toxin is most concentrated in the liver, ovaries, and skin of the fish, and there is no widely available antidote; management is supportive, focusing on securing the airway and supporting breathing and circulation. Staphylococcus aureus involves bacteria that produce enterotoxins causing food poisoning, not a toxin from puffer fish. The other options refer to nonbiological items (like a temperature sensor) or food preservatives, which do not characterize puffer fish poisoning.
