1. Is pufferfish poisonous?

The body of a pufferfish is short and thick. It has small hair-like spines. The tough and thick skin of a pufferfish was once used to make helmets. The teeth of the upper and lower jaws of a pufferfish are connected together, like a sharp blade. This allows the pufferfish to easily bite the shell of hard corals. Most pufferfish are tropical marine fish, and only a few species live in fresh water. Once a pufferfish is threatened, it will swallow water or air to swell its body into a spiky ball, making it difficult for its natural enemies to bite it. The internal organs of many types of pufferfish contain a neurotoxin that can kill people. Someone has measured the toxicity of pufferfish toxin. Its toxicity is equivalent to 1,250 times that of highly toxic drugs, and only 0.48 mg is needed to kill a person. In fact, the muscles of pufferfish do not contain toxins. The most toxic parts of a pufferfish are the ovaries and liver, followed by the kidneys, blood, eyes, gills and skin. The toxicity of a pufferfish is also related to its reproductive cycle. Pufferfish carrying eggs in late spring and early summer are the most toxic. This toxin can cause nerve paralysis, vomiting, cold limbs, and then cardiac and respiratory arrest. There are reports of people dying from eating pufferfish both at home and abroad. Although tasting pufferfish is life-threatening, many greedy people still eat pufferfish at the risk of their lives because it tastes very delicious. The country in the world where pufferfish is most popular is Japan. There are pufferfish restaurants in major cities in Japan. Chefs must undergo strict professional training. During the graduation exam, chefs must eat the pufferfish they cooked. Therefore, some people who are not skilled enough dare not take the exam and run away. Pufferfish swim very slowly. This is because most fish usually have swimming muscles in the back half of their bodies. Pufferfish have to use their dorsal and caudal fins that swing left and right to paddle. Pufferfish teeth are very similar to those of porcupines. Pufferfish teeth are fused into a beak. The upper and lower osprey teeth are used to bite mollusks and corals. Pufferfish swallow the living parts of these creatures together with marine life such as crabs, worms and barnacles. The poisonous component of puffer fish is tetrodotoxin, which is a neurotoxin. If a person ingests 0.5mg-3mg of tetrodotoxin, it can be fatal. The liver, spleen, kidney, ovary, testicle, eyeball, skin and blood of puffer fish are all poisonous. The eggs, ovaries and liver are the most poisonous, followed by kidneys, blood, eyes and skin. The toxin is heat-resistant and will not be destroyed for 8 hours at 100℃, but will be destroyed for 1 hour at 120℃. Salting and sun exposure cannot destroy the toxin. Every spring is the spawning season of puffer fish, and the toxicity of fish is the strongest at this time. Therefore, spring is the high-incidence season of puffer fish poisoning. my country's "Regulations on the Hygiene Management of Aquatic Products" clearly stipulates: "Puffer fish is highly toxic and shall not be allowed to enter the market. Caught poisonous fish, such as puffer fish, should be picked out and packed in boxes and stored in a special fixed place." Therefore, it is better not to eat puffer fish. Only a few people risk their lives to eat puffer fish, but most people are poisoned because they accidentally eat puffer fish because they do not know puffer fish.
