A few days ago, some netizens found the blue-ringed octopus in the dishes of a hot pot restaurant, which attracted the attention of netizens. 65438+1October17th, a Shenzhen netizen posted that his family bought a box of frozen octopus in Futian store in Sam a few days ago and found a blue-ringed octopus in it after opening it. The staff of Futian Store in Sam said that all the octopus in the store are farmed artificially in China, so the probability of blue-ringed octopus is very low, and relevant parties will be contacted to verify the situation.

Before the dishes in the hot pot restaurant were shocked by the blue-ringed octopus, some netizens found the suspected blue-ringed octopus while eating barbecue. Now, it is reported that this kind of octopus has been found in the frozen food in the regular supermarket, and the poisonous blue-ring octopus appears in chains, which is hard to prevent and makes seafood diners feel uneasy. Some netizens said, "Is this the nest of the blue-ringed octopus?" Some netizens also said that in order to cherish their lives, they would never eat octopus again.

Natural History magazine, which had previously helped the network identify the blue-ringed octopus, only published a popular science article, because it received too many private inquiries from people who were worried about meeting the blue-ringed octopus, reminding everyone to raise their awareness of prevention and not to be afraid of danger. It can be seen that this incurable super poison has generously appeared in dining tables and supermarkets, which has had a great impact on everyone's sense of security.

Therefore, although the business staff repeatedly stressed that the probability of the blue-ringed octopus appearing in the store is very, very low, I feel that I can't wait for the next sentence, saying that this octopus may not be from our store, but it may also be a netizen. Of course, it is really impossible to draw a conclusion about the origin of the blue-ringed octopus until the relevant information is verified, but you should know that a small blue-ringed octopus carries enough toxins to kill 26 adults at one time in a few minutes, and there is no effective antitoxin to prevent it at present. Such terrible things are mixed into food in various forms, even if the probability is low, we should be vigilant, because once someone eats by mistake, the consequences will be unimaginable. The food safety defense line should be indestructible, and we can't talk about "probability" as soon as something goes wrong.

This netizen sent it to Weibo.

To be sure, the blue-ringed octopus is definitely not a common creature, otherwise there would not be so many people who don't know it. However, the blue-ringed octopus, which had a very low probability of appearing, has appeared frequently recently, which is really worthy of questioning and vigilance. At present, whether in regular restaurants, supermarkets or roadside stalls, this highly toxic creature may appear. Is this the same batch of goods? Are there any other blue-ringed octopus still circulating in the market? Which link lost contact, causing toxic octopus to mix with edible octopus? Food safety is a very important matter. Now, it seems that not only hot pot restaurants and supermarkets involved need to trace the source of goods, but also the market supervision departments in the developed areas of seafood industry should take action to thoroughly investigate the hidden dangers of food safety risks, find and plug possible loopholes, and relieve people's anxiety caused by poisonous octopus.

China has completely fasted wild animals, but catching natural fishery resources such as fish is an important mode of agricultural production, and aquatic wild animals such as fish are not within the fasting range, which opens a gap for many poisonous marine creatures to swim to the table. However, the law still clearly stipulates that it is forbidden to operate foods that do not meet the food safety requirements, especially toxic and harmful foods. Catering service providers shall formulate and implement raw material control requirements, and shall not purchase food raw materials that do not meet food safety standards. This requires suppliers and merchants engaged in seafood catering to have professional identification ability and a sense of responsibility to ensure safety. It cannot be said that customers can rely on multiple thinking or extensive knowledge to "save themselves".

Fortunately, the characteristics of the blue-ringed octopus are very obvious, and it is easy to find that after this wave of popular science, I believe that the risk of eating by mistake will be greatly reduced. But in the long run, the relevant departments still need to pay enough attention to the problem of this highly toxic creature appearing in the market circulation. For this highly toxic creature, there should be corresponding regulations on how to distinguish it when fishing, how to avoid being hurt, and how to deal with it after discovery. Only by letting more people, especially food operators, know the serious harm of these highly toxic organisms and what to do if they find them, can we strengthen the supervision of the whole chain, effectively build a food safety defense line and protect people's lives, health and safety.

Eating hot pot meets poisonous blue-ringed octopus, and a lot of food is hidden.

Yesterday, a news about the blue-ringed octopus attracted attention.

When some netizens were eating hot pot, they found that there was a kind of suspected blue-ringed octopus in the dish. He took photos and asked popular science bloggers, and it was later proved to be a blue-ringed octopus, which is highly toxic.

This incident also quickly rushed to the hot search, which triggered a heated discussion. Some netizens ridiculed that "knowledge changed fate."

But more netizens are curious, what is the blue-ringed octopus? How did it appear on the dining table? What other foods are hidden "killing"?

The blue-ringed octopus rushed to the hot search.

"Is this a blue octopus? Can I cook? Waiting online is a bit urgent! "

65438+ 10 16, a netizen posted in Weibo that he saw a spotted creature that looked like an octopus in a hot pot restaurant, and asked the popular science blogger @ Natural History Magazine.

Subsequently, @ Museum Magazine replied: "It is indeed a leopard octopus. Their toxin is river toxin, which is very toxic and will not decompose after heating. Don't eat it even if you take it back as a souvenir. There are records in the literature and online that octopus and blue-ringed octopus live together, but the probability is not high, which is considered to be a longevity scene. "

Under the reminder of the blogger, the netizen also said that he would not eat this dish and had asked the boss to withdraw it. Netizens also commented: "This is a brush with death!" "I want to remember what this octopus looks like."

Relevant information shows that the blue-ringed octopus belongs to the octopus family, commonly known as the blue-ringed octopus, the leopard octopus and the leopard octopus. It is widely distributed in the Taiping sea area between Japan and Australia, and it is a very small octopus species with an arm span of less than15cm. In the ocean, the blue-ringed octopus is one of the highly toxic creatures, and being bitten by this small octopus will lead to death.

The toxicity of the blue-ringed octopus can be shown by color. In different environments, it will become a protective color similar to the environment. Once it feels threatened, its skin color will become gorgeous. When the blue ring flashes, it is also the most dangerous time. It's on alert. Generally speaking, the blue-ringed octopus is gentle, but it can also sting and bite when threatened.

The toxins secreted by the blue-ringed octopus contain tetrodotoxin, hyaluronidase, histamine, tryptamine, hydroxyaniline, taurine, acetylcholine and dopamine, among which tetrodotoxin is the main toxic substance. This toxin can block sodium channels in muscles, paralyze muscles and lead to respiratory arrest or cardiac arrest.

At present, the laws of China do not stipulate the sale and transportation of highly toxic wild animals such as the blue-ringed octopus, and the relevant regulations on rare and endangered wild protected animals do not include the blue-ringed octopus.

On the contrary, due to its charming appearance, the blue-ringed octopus was once the "darling" of the pet industry. As early as 20 16, there were media reports, and some netizens said that they could buy live blue-ringed octopus on the e-commerce platform. Blue-ringed octopus is one of the most toxic marine creatures in the world.

Seafood and wild mushrooms are the "hardest hit areas"

In addition to the blue-ringed octopus, what other poisonous creatures that are easy to appear but unfamiliar in life need attention? Yue, the operation editor of Natural History magazine, said in an interview that seafood and wild mushrooms can be said to be two "hardest hit areas".

Speaking of poisons in seafood, the most famous one is puffer fish. Yun Orfila, a doctor of food engineering and a popular science writer, said that tetrodotoxin is an aminotetrahydroquinazoline compound and one of the most toxic neurotoxins found in nature. "The toxicity of tetrodotoxin is about 70 times higher than that of arsenic, and a few milligrams can poison a person. It can inhibit sodium channels in human body, make people unable to breathe, and poison people by affecting muscle contraction. Tetrodotoxin can attack in just a few minutes or ten minutes, and the longest is only a few hours. "

Many poisonous organisms may disappear after being heated and cooked, but tetrodotoxin is different. Yun unintentionally said that tetrodotoxin is a non-protein toxin. No matter how heated, its toxicity reduction is very limited. Even if the food is cooked thoroughly, it will still cause poisoning after eating.

In addition, the shellfish we eat every day may also become latent "assassins", such as Haihong. The scientific name of Haihong is mussel, and there are mussels, mussels, mussels and other names everywhere. Sea red is a kind of cheap seafood, which often appears on people's tables everywhere.

Sea red itself is non-toxic and can be eaten by regular cooking under normal circumstances. The reason why toxins appear is mainly related to a well-known phenomenon-"red tide". When a red tide strikes, Haihong eats phytoplankton containing toxins. It will not be poisoned by itself, but it can concentrate the toxins into the body. People may be poisoned if they eat this sea rainbow.

Haihong is not the only seafood rich in toxins, but also seafood that feeds on plankton such as scallops, oysters and clams. Experts suggest that when eating shellfish, the digestive glands and other internal organs should be removed to minimize the number of times of eating, and it is not advisable to eat too much at a time.

In addition to seafood, food poisoning caused by eating poisonous wild bacteria by mistake is also very common. There are many toxic species and complex toxic components in wild mushrooms. Some folk methods to identify wild mushrooms have been proved to be unreliable.

In June of 20021year, the article published by China Center for Disease Control and Prevention showed that during the period from 20 10 to 2020, there were a total of 10036 cases of food-borne mushroom poisoning in China, resulting in 38,676 cases of illness, 2 1967 cases of hospitalization and 788 deaths. Among them, Yunnan reported the largest number of poisoning incidents, diseases and deaths.

More food poisoning occurs in family scenes.

Liu, a doctor of food safety and a member of the expert group of Shanghai Food Safety Research Association, told the reporter of China Newsweek that, on the whole, the probability that consumers are exposed to toxic seafood and fungi is relatively low, and what really needs to be careful is bacterial food poisoning caused by improper cooking or storage. Such cases abound in real life.

On June 5, 2020, 10, a family in Jixi, Heilongjiang Province ate sour soup and caused food poisoning, which eventually killed 9 people.

According to reports, because the refrigerator can't hold it, the frozen sour soup was taken out of the refrigerator and placed in a cool and humid place for a few days, which eventually produced rice yeast acid. At present, there is no specific medicine, and the mortality rate after poisoning is 40%- 100%.

Soaking black fungus for a long time is also easy to cause poisoning. According to Wuhan Evening News 20 19, a mother and daughter in Wuhan began to have abdominal pain and vomiting after eating black fungus mixed vegetables soaked for two days and nights. It turns out that Auricularia auricula may breed Pseudomonas cocoanum in the process of long-term foaming, and it will also produce rice yeast acid, which will lead to poisoning.

Aflatoxin is also one of the common toxins. As early as 1993, aflatoxin was listed as a kind of carcinogen by the Cancer Institute of the World Health Organization, and it is a highly toxic substance. 1 mg is a carcinogenic dose.

Aflatoxin likes to hide in moldy foods, especially peanuts, corn and beans with high starch content. In high temperature and humid environment, aflatoxin causing liver cancer will breed. If peanuts are moldy, the whole bag of peanuts should be thrown away, because Aspergillus flavus spreads in the form of spores, and food is easily involved in mildew.

Because ordinary people are prone to problems in food safety control and production methods, families have become a high-incidence scene of food poisoning. According to media statistics, the probability of accidental discovery of food poisoning at home was as high as 46.5% in the places where food poisoning occurred in China from October 2008 to October 2008.

"At present, the year is approaching, which is the node for buying and making vegetables and meat in large quantities. Be more careful about food safety. " In this regard, Liu Shaowei suggested that in the process of food processing, raw and cooked foods should be treated separately, using different chopping boards and different knives, and never mixing raw and cooked foods; In the process of food cooking, improper treatment of temperature and time, lack of sufficient cooking temperature and time may lead to food poisoning due to the inability to kill germs in food; Expired food and some leftovers must not be reluctant to throw away because of thrift and fear of waste.
