Tetrodotoxin is a neurotoxin that can be found in several fish species. One of the most famous fishes that carry this poison is puffer fish also known as Fugu fish. Many of you will be familiar with the latter name since the meal prepared from this fish is being marketed as a delicacy in Japanese restaurants. The thing is that such meal could be your last if the fish is not prepared correctly. The chefs that are allowed to prepare it have to train for years. Our sources say that this poison should be on the list because of its deceiving factor. Although it is easily traceable in the body, not many will suspect at murder and could regard it as a food poisoning. The victim would just really need to crave for a sushi. Don’t get any ideas, out of this unless you writing a book or planning a TV show. In that case, we want our cut.
