Fugu is a delicacy in Japan, prized for its delicate flavor and the thrill of its danger. But it contains tetrodotoxin, a potent neurotoxin found in the fish’s liver, ovaries, skin, and intestines—up to 1,200 times more lethal than cyanide. Just one milligram can kill an adult human, and there’s no known antidote.
🐡 Why Is It So Dangerous?
- Tetrodotoxin blocks nerve signals, leading to paralysis, respiratory failure, and death—often within hours.
- Cooking, freezing, or drying does not destroy the toxin.
- The toxin is odorless and tasteless—you won’t know you’ve ingested it until symptoms begin.
