8.Fugu
A Japanese delicacy, Fugu is almost banned in the U.S. since it is very poisonous. Also known as pufferfish, its liver, intestines, and ovaries contain tetrodotoxin which is a deadly poison. While it is technically not banned, the chefs that prepare this delicacy have to train for up to three years in order to obtain the license to serve it. Despite being highly poisonous, it is a very expensive dish, and if you want to try it, there are only a few restaurants that serve it.
