The fugu (河豚; 鰒; フグ) in Japanese, bogeo (복어; -魚) or bok (복) in Korean, and hétún (河豚; 河魨) in Standard Modern Chinese is a pufferfish, normally of the genus Takifugu, Lagocephalus, or Sphoeroides, or a porcupinefish of the genus Diodon, or a dish prepared from these fish. Fugu possesses a potentially fatal poison known as tetrodotoxin, therefore necessitating meticulous preparation to eliminate poisonous components and prevent the fish meat from being contaminated.The restaurant preparation of fugu is strictly controlled by law in Japan, Korea and several other countries, and only chefs who have qualified after three or more years of rigorous training are allowed to prepare the fish. Domestic preparation occasionally leads to accidental death.Throughout Japan, fugu is served as sashimi and nabemono. The liver was served as a traditional dish named fugu-kimo, being widely thought to be a tasty part, but it is also the most poisonous, and serving this organ in restaurants was banned in Japan in 1984. In the gastronomic domains of East Asian cuisine, fugu has emerged as a highly renowned delicacy, garnering widespread acclaim in establishing itself as one of the most celebrated dishes in Japanese and Korean cuisine. Fugu has also been gradually emerging as a prized seafood delicacy in the Chinese culinary landscape as well. Source: Wikipedia (en)
