I went to the beach before and saw a lot of puffer fish in the water, and it was particularly good to catch, but I regretted it when I was catching it. I accidentally got bitten by it and it was bleeding fast, and at that time I felt like I was dying. With the mindset of certain death, I went to see the doctor, who asked for clarification and went straight to the next person.

"Doctor, you mean I am I hopeless?"

The doctor a blank stare, let me experience ......

The reason why the puffer fish is highly toxic is because of the presence of tetrodotoxin. The toxicity of tetrodotoxin, which you should have heard of, is 1,250 times more toxic than potassium cyanide, and it only takes 0.48 milligrams to kill a person. After poisoning, it takes only 10 minutes at the earliest to die.

Tetrodotoxin is mainly distributed in is ovaries, liver, followed by kidneys, blood, eyes, gills and skin, etc., if in accordance with the toxicity of the arrangement is this: ovaries & gt; spleen & gt; liver & gt; blood & gt; eyes & gt; gills & gt; skin & gt; spermatic ovaries. (Pufferfish females are more toxic, and the sperm nests are also considered a delicacy because of their low or no toxicity.)

So tetrodotoxin may also be present in pufferfish blood.

So can you be poisoned or even die if you have tetrodotoxin stuck on your hands?

Tetrodotoxin is a neurotoxin, which can prevent sodium ions from transmitting nerve signals through cell membranes, thus shutting down the human nervous system, but tetrodotoxin can't get past the brain's defenses, so after the poisoning, the person will remain conscious and awake, waiting for death. The tetrodotoxin has a certain time limit, if people can survive, it is possible to save a life.

Unlike cyanide, which is poisoned by direct contact, tetrodotoxin is not poisoned by direct muscle contact, unless there is a wound on the hand. Therefore, contact with tetrodotoxin blood is not poisonous.

Tetrodotoxin accumulates mainly through seaweed intake, and in artificially farmed pufferfish, tetrodotoxin is basically gone, so you can use it without worry.

What, all can not stop a foodie heart!

Fun and interesting science knowledge, welcome to pay attention to the girl!

Farmed puffer fish.

Tell you responsibly: yes! But not right away.

Generally speaking it also depends on whether the encountered wound has broken skin, how the contact person's body resistance, the future routine eating structure balance problems, if the situation is worse, according to the current medical conditions of the current mainland, the contact person has a 90% chance of dying within 29,200 days.
