Puffer fish from all other sources potentially contain deadly toxins and therefore are not considered safe. The liver, gonads (ovaries and testes), intestines, and skin of some puffer fish contain the toxins tetrodotoxin and/or saxitoxin.
Most pufferfish contain a toxic substance that makes them foul tasting and potentially deadly to other fish. The toxin is deadly to humans. There is enough poison in one pufferfish to kill 30 adult humans, and there is no known antidote. In Japan, they are called fugu and are a very expensive, delicious treat.
