Hai Yan soft cute is delicious?It is miserable to be injured by it, serious and fatal!

Cold -mixed sea crickets, refreshing and appetizing, are the favorite of many people. However, although the long -term human and animals are harmless, it is still a terrible creature for people living in the coastal areas.

If it is injured by it, it will be uncomfortable for several days, and it may be fatal. Why is the "poison"? What about nutrition after being made into food?

01

What kind of creature is the sea?

Hydroma is a spine -free animal animal. It belongs to the jellyfish. It is eaten with floating creatures, small crustaceans, multi -haired and even small fish. Mainly living in coastal areas in my country, from the coast of Guangdong and Hainan Island to Liaoning. [1]

The sea cricket has a round umbrella or bell -like body, with touches and mouth wrists. The surface of the outer umbrella is smooth, the middle glue layer is thick and hard, and the large sea umbrella can reach 25 ~ 60 cm [2]; the touchpad is a digestive organ and a weapon for hunting. There are many poisonous wires that can shoot venom.

What will happen to the harm of the sea?

The appearance of Haiyu seems to be soft and cute, but human and animal is harmless, but it is a "toxic killer."

Every year from June to October, the seafood will be floated to the surface of the water, and these months are also the hottest weather in the past few months. Many people will go to the beach. It's easy to be injured. [3]

In August 2015, in the Xiajiahezi seaside bath in Dalian City, Liaoning Province, a 4 -year -old girl died unfortunately by the sea of ​​sea. The girl's mother was injured because she kicked her kick.

Hydium is very toxic, and its tentacles are covered with poisonous wires, which can shoot venom. The toxic ingredients are jellyfish toxins. When the human body is exposed to the tentacles of the sea crickets, the barbed sac will immediately release a large number of jellyfish toxins, causing the human body to have poisoning symptoms, such as contact dermatitis, itching and pain, skin congestion, and even local necrosis. The symptoms of itching and pain can last for 10 to 20 days, and severe ones may not heal for a few months. [4, 5]

Not just a seafood, many jellyfish are not easy to provoke.

If it is severely injured by a seafood, it will cause systemic symptoms, such as cough, chest tightness, asthma, exercise disorders, heart failure, vomiting, diarrhea, liver and kidney damage, etc., which will cause allergic shock. [4, 5]

Statistics in my country show that about 2,200 cases of sea cricket stinging in the coastal tourism area have occurred in the past 20 years, and 13 of them died. The cause of death was allergic shock after the injury. [4]

If the cardiovascular system is infringed, syncope and shock may occur in just a few minutes or even 1 minute. The skin changes from pale to hair, which can cause death in a short time. [4]

03

What should I do if I was injured by a sea?

There is no special effect of sea injuries to be treated. If you are unfortunately injured, you should immediately take measures to relieve it.

You can remove the sacral sac that can be removed by a tadar, and then rinse the stingy area with the seawater. Do not rinse it with fresh water, because the fresh water's osmotic pressure is low, which can cause the stabbing sac burst to release toxins and aggravate the symptoms. Don't wash it with vinegar, otherwise you may increase pain, let alone squeeze the injury with your hands. [4]

After simple treatment, you should go to the hospital immediately for the corresponding treatment.

04

What is the nutrition of Haiyu?

Haiyu is edible, and my country is the earliest country to eat and use Haiyu. The traditional processing method is to be impregnated with lime and alum, and then squeeze the moisture, washing, and marinating in its body. After treatment, it becomes the usual seafood products. [6]

After the umbrella cover is processed, it will turn into a round and translucent skin, which is the sea of ​​sea crickets;

The most common dishes are cold seafront shreds (filaments cut by sea tadpoles), cold -mixed sea ravioli, and crispy taste, which is the favorite of many people.

Tuwa Creative

Both seafood skin and sea bulls are low -fat, low cholesterol foods, and even people with abnormal obesity and blood lipids can be eaten at ease.

In addition, the calcium content of the minerals of the sea crickets is relatively prominent. The calcium content of the seafood skin and the head of the sea bulls is 150 mg/ 100 grams and 120 mg/ 100 grams, respectively, which is excellent in aquatic products. If you eat 100 grams of cold sea filaments, it can meet the 19 %demand for calcium throughout the day, which is still good. [7]

The purine content of the sea is also very low. The total purine content is only 9 mg/ 100 grams. It belongs to low purine foods. High uric acid people and crowds of gout can be eaten with confidence. [7]

In addition, it is necessary to remind: Don't think that the seafood is rich in collagen to eat and beauty.

Therefore, don't expect to eat the beauty of the sea, but you can supplement calcium, and the taste is also good.

Summarize:

Although Hai Yan tastes delicious, it is really far away if you encounter it by the sea, don't catch it. Don't touch even the death of the sea, be careful of being injured by it.
