1. Fugu (Pufferfish)
Fugu, a Japanese delicacy, contains tetrodotoxin, one of the deadliest natural poisons in the world. Just a tiny amount can paralyze the nervous system and stop breathing. Only licensed chefs, trained for years, are allowed to prepare it in Japan. Safe preparation requires meticulously removing the liver, ovaries, and skin, where toxins are concentrated. When cleaned correctly, the remaining meat is considered safe to eat and prized for its delicate flavor.
How to enjoy without risk: Only eat fugu prepared by certified, licensed chefs—never attempt it yourself.
