Knowra Fugu Fugu Fugu is Japanese cuisine made from pufferfish, whose organs can contain tetrodotoxin. In Japan, specially licensed chefs prepare it under rules intended to prevent poisoning.
Tetrodotoxin : A potent neurotoxin that blocks voltage-gated sodium channels and can cause paralysis. It is the toxin that makes some pufferfish organs hazardous to eat.
Fugu sashimi : A dish of thinly sliced raw pufferfish, often arranged in a decorative pattern. It is a well-known way to serve the fish's mild, firm flesh.
Edo period : The period of Japanese history from 1603 to 1868, when the Tokugawa shogunate ruled. Fugu eating traditions developed within the long history of Japanese urban food culture.
Sushi : A Japanese dish centered on vinegared rice, often combined with seafood or other ingredients. Fugu sashimi is raw seafood, but it is not sushi unless served with sushi rice.
Voltage-gated sodium channel : A membrane protein that opens in response to voltage changes, allowing sodium ions to cross cell membranes. Tetrodotoxin causes paralysis by blocking these channels in nerve and muscle cells.
Tecchiri : A Japanese hot pot made with pufferfish, vegetables, and broth. This cooked fugu dish contrasts with raw preparations such as sashimi.
Yamaguchi Prefecture : A prefecture in western Japan, located at the western end of Honshu. Shimonoseki is a major center of pufferfish commerce and a prominent fugu destination.
Blowfish poisoning : Acute poisoning caused by ingesting tetrodotoxin from pufferfish or contaminated food. It is the dangerous outcome fugu preparation rules are designed to prevent.
Pufferfish : A family of fish that can inflate their bodies and, in many species, accumulate tetrodotoxin. The fish supply fugu, and toxin distribution differs among species and organs.
Fugu milt : The sperm sacs of male pufferfish, served as food in some Japanese cuisines. It is a prized fugu ingredient that must be distinguished from toxic organs.
