Common problems in eating puffer fish
Eating salmon and puffer fish together is life-threatening. If puffer fish avoid incense ashes when eating, they will die of poisoning.
Generally speaking, the head, skin, eyes, blood and internal organs (especially uterus, ovary and liver) of fresh puffer fish contain toxic substances, which are called tetrodotoxin and belong to the toxic category. The lethal dose of tetrodotoxin to adults is 300 mg. The puffer fish that has been dead for a long time must not be eaten, because the endotoxin in the viscera will slowly penetrate into the muscles. Some puffer fish are harmful not only to internal organs, but also to muscles. This endotoxin cannot be removed by ordinary cooking methods. It is best not to cook and eat puffer fish by yourself. Relatively speaking, it is safer to eat puffer fish in reliable hotel restaurants, because some restaurants will hire old masters who kill puffer fish at high prices to solve puffer fish professionally.
