Haihong is a very common food in the northern region, it can be said that most people have eaten it, haihong is also called mussels, but this kind of food that people love, and is eaten on a large scale - but it has "poison", what is the situation? And this kind of poisoning incidents have been reported worldwide, the United States, Japan, China and other places have relevant reports, in March to September every year belongs to the high incidence of poisoning incidents, China's poisoning incidents are mainly concentrated in Zhejiang, Guangdong and other places.
In the past few days, many places in the north of China have issued early warnings of fasting haihong, such as Cangzhou City, Qinhuangdao City, etc., which also shows that poisoning incidents are gradually entering a high incidence period, so do not eat is the safest, let's take a look at the specific situation.
<h1 class="pgc-h-arrow-right" data-track="12" > Haihong</h1>
Haihong is also called mussels by us, and there is the title of "Lady of the East Sea", Haihong is very common in the north of our country, many areas can be said to have its footprints for three meals a day, and Haihong's eating methods are also very much, stir-frying, steaming and other ways can be used. But every year, you should also know that there is a period of prohibition on eating, and different provinces are different. Qinhuangdao banned the consumption of haihong this time, mainly through the characteristics of the creature.
This period is mainly because the sea rainbow will produce a paralytic shellfish toxin during the day as the temperature rises, so it is very easy to cause poisoning, which will cause breathing to stop and be fatal. So the rainbow does belong to a dangerous food today, the appearance of the food is generally black brown, mainly in China's Yellow Sea, Bohai Sea and East China Sea coast more, the southern region is relatively rare, the general shell length of 6 to 8 cm, shell length is less than 2 times the shell height, under normal circumstances, is directly used for cooking, do not carry out any treatment.
Of course, now is the high incidence of rainbow poisoning, so really to eat, not too much at a time, at the same time to carry out scientific treatment, otherwise the poisoning may not know itself. However, under normal circumstances, it is recommended not to eat, which has a greater impact on the body.
<h1 class="pgc-h-arrow-right" data-track="12" > how toxic is Haihong, why not ban it directly? </h1>
At the beginning, many people also wondered why Haihong had time to eat, time not to eat, whether it was poisonous? This question has indeed been hotly debated in the scientific community for a long time, and it was in 1928 that scientists discovered that the problem of whether the rainbow is toxic or not is completely with seasonal changes.
At the same time, the sea rainbow itself is not toxic, the reason why it appeared toxins in March to September is because as the temperature rises, the paralyzing shellfish toxin content in the sea rainbow gradually increases, and the source of this toxin comes from the red tide, so it is not a problem of the sea rainbow at all, but a seasonal toxin problem, which does not need to be directly banned.
Simply put, the poison of the sea rainbow comes from the red tide, of which the algae of the Knee Groove Algae (Conylaceae) is the most severe, after the large number of reproduction and the formation of the so-called "red tide", it will be absorbed by the sea rainbow, etc., but this is harmless to the sea rainbow or shellfish itself, but it will be concentrated in the organism, so after people eat shellfish, the toxin is quickly released and poisoned. Nowadays, a variety of similar toxins have been found in the rainbow or in the case of shellfish poisoning, such as new stone clam toxin, knee groove algae toxin and so on.
Among them, PSP (sax toxin) is more toxic, generally after eating toxic shellfish, signs of poisoning occur within 30-60 minutes, and occasionally there are cases of 3 hours or more. In general, the mortality rate is only 6%, but the serious poisoning is as high as 44%, so the toxicity is very strong, and the toxicity of the toxin is 80 times that of the cobra venom, and the terrible thing is that there is no antidote to this toxin, so it is necessary to issue a ban on eating the Red Sea time period today.
And poisoning is not only rainbow species, common poisoning species include clams, snails, oysters, scallops and so on. After poisoning, it is generally manifested as symptoms such as paralysis of the limb muscles, headache and nausea, salivation fever, rash, etc., which is the general situation. So here is also a reminder to everyone, in the stage of red tide, we are best not to dip all shellfish, because most of the shellfish contain the possibility of toxins, coupled with many people do not know the classification of these shellfish, it is more likely to lead to a high incidence of poisoning events.
<h1 class="pgc-h-arrow-right" Data-track="12" Why is there a red tide >? </h1>
China is one of the countries most affected by red tide, and the reason for the red tide phenomenon in the ocean is still relatively many factors, the most typical is that human activities have a greater impact. With the emergence of the era of industrialization, modern industry, agricultural production and other large-scale development, and a large number of agricultural, industrial wastewater discharged into the ocean, so the marine environment is polluted, providing favorable conditions for red tide, they prefer "polluting" water quality, but also conducive to growth.
Therefore, the more serious the pollution in the area, the easier it is to see the occurrence of red tide, and the red tide phenomenon along the Yangtze River estuary and Zhejiang coast of China is more and more, of which the longest red tide phenomenon can last for 35 days, with a cumulative area of more than 10,000 square kilometers, so the harm is extremely great. After this happened, we saw large-scale fish deaths, also because the emergence of red tides led to a lack of oxygen in the ocean waters, so the biological population could not survive, which is why.
This has to be said that the impact of red tide on human beings is very huge, but when it comes to the root cause, it is still because of human beings themselves, and the pollution of the environment will not be so serious, and the number of red tides will continue to grow explosively in the world over time, and there is no effective way to control it for the time being, so now "silence" is the most critical problem.
