Fugu is a puffer fish prized by Japanese fish connoisseurs. Its liver is poisonous, thus only specially-trained chefs can serve it. A episode of The Simpsons featured Homer poisoned by fugu.
Recently, however, researchers determined that fugu liver is poisonous because fugu eat poisonous food. When fugu is farmed, and given non-poisonous food, its liver is harmless, and the fish tastes almost as good. No more need for special processing. Unsurprisingly, the National Fugu Association wants to preserve the status quo. But you can now buy fugu liver in the town of Useki.
Masataka Kinashi, the head of the tourism association in Usuki and a fugu dealer himself, suddenly stared down at his desk when asked about the widespread sale of fugu liver.
â€œOfficially, you can never eat it here,â€ Mr. Kinashi said. â€œWell, itâ€™s not that you canâ€™t eat it, but, no, you canâ€™t eat it. Thatâ€™s the only answer I can give you.â€
