Hello, let me help you answer this question!

There is a folk proverb called "summer is the supplement, eel comes first" and "eel competes with summer ginseng". So eating Monopterus albus in summer is very popular in many places. In Hangzhou on the tip of the tongue, fried shredded eel has always been a very popular dish.

However, a recent online article about Monopterus albus made many foodies sit still. Because its title is "deadly parasite in Monopterus albus, dear, are you still eating?" ",the article repeatedly stressed: Don't eat eel raw! The parasite gets into the eye and there is no medicine to solve it.

Yesterday, CCTV news channel reported that both domestic and wild Monopterus albus had jaw nematodes. Push this topic to the forefront again, can eels still be eaten?

Experts from the Institute of Parasitology, Zhejiang Academy of Medical Sciences have concluded that the rumors are not completely reliable, and eels can be eaten! But be sure to cook!

Qianjiang evening news reporter learned that the Institute of Parasitology of Zhejiang Academy of Medical Sciences is the earliest professional research institution of parasitic diseases in China, and it is also the earliest institution that can detect oral nematodiasis in China.

Monopterus albus has many parasites, does it really include jaw nematodes?

Expert: 250 live worms were isolated from 10 kg Monopterus albus.

Online originality:

One day, my father bought more than a catty of eel from the market. When he killed the eel, he found that there were many moving insects in it. It looked disgusting and my father didn't dare to eat it.

Oral nematodiasis is one of the most dangerous parasitic diseases, with a long incubation period and constantly wandering in the human body. Once it enters the human brain, it is very dangerous, which may cause serious headache, epilepsy, fainting and even death.

What parasites are there in eels?

Experts say:

This is not sensational. Monopterus albus does have parasites.

It is understood that because Monopterus albus likes to dig holes in the mud and feed on small fish and shrimp, such living habits and food composition determine that Monopterus albus is easy to breed parasites. The jaw nematode mentioned in the post is one of the parasites.

As early as two years ago, the project "Establishment and application of immunodiagnostic methods for oral nematodiasis" by Institute of Parasitology, Zhejiang Academy of Medical Sciences was approved by Zhejiang Provincial Health Department, and the recent results have come out. Ma An, a staff member of Institute of Parasitology, is a member of the research group. "Now the results have come out and I am writing related papers."

When doing the project, they specially went to places with frequent cases to purchase Monopterus albus, including Hangzhou, and went to five or six farmers' markets to purchase 10 kg Monopterus albus. Results A total of 250 live nematodes were isolated. "Oral nematodes exist not only in the internal organs of Monopterus albus, but also in the muscles, with the liver being the most located." The harm of Nematoda gigantea is really obvious, because it can survive in the human body for several years, and it will swim all over the body, which will bring damage to tissues and organs wherever it swims. "Especially the brain is the most harmful and life-threatening." Ma An said.

Once you get oral nematodes, the chances of recovery are extremely small?

What parasites are there in eels?

Expert: There is a specific medicine that can kill this parasite in two days.

Online rumors:

Humans eat fish with jaw line larvae, just like a lost headless fly, running around in the human body, with strong vitality. At present, in China, there is no drug that can completely cure the disease, and only temporarily control the disease. Fortunately, bugs can escape by themselves.

Experts say:

Not exactly. There is a specific medicine, and the medicine will cure the disease.

Ma An said that the treatment of oral nematodes is not complicated. "There is a specific drug for the treatment of oral nematodiasis in the world, called ivermectin, which is produced in the United States. As long as you eat it for 2 days, you can basically kill insects. You can also eat albendazole (intestinal worm removal), but you have to eat it for 20 days. "

However, jaw nematodes were originally mainly distributed in Southeast Asian countries. Compared with the domestic incidence rate, the incidence rate is very low, so there are few related studies, and no pharmaceutical company has specially developed similar drugs. Ivermectin is rarely seen in major hospitals. "This medicine is not sold in China. Patients diagnosed with E.coli in Hangzhou finally bought this medicine through friends in the United States. " Ma An admits that there is also a situation where patients can't wait for medicine, so they are in danger.

Compared with treatment, diagnosis often takes some time. For example, a patient in Hangzhou once had a red and swollen lump on his skin, which was considered as herpes zoster by the hospital. There is no effect after taking antiviral drugs. He was transferred to a dermatological hospital and was diagnosed with eczema until he was finally diagnosed in the Institute of Parasitology, Zhejiang Academy of Medical Sciences. I used it for nearly two months before and after.

Is it difficult to kill the parasites in Monopterus albus by conventional cooking methods?

Expert: Cook thoroughly at high temperature, and be especially careful when frying.

Internet rumors:

Every year at the turn of spring and summer, it is the peak season to eat Monopterus albus, but you may not know that there are many parasites in Monopterus albus that cannot be killed by cooking. You can see these parasites with the naked eye when cutting eel!

Experts say:

Yesterday afternoon, a reporter from qianjiang evening news rushed to the farmer's market in Feng Ping Street, Zhonghe North Road, and bought two eels. I saw that the stall owner quickly grabbed one, weighed it and put it in the washbasin. Pick up a pair of scissors and cut a hole in the head of Monopterus albus, then cut the body of Monopterus albus with scissors and pull out the internal organs. During the whole process, qianjiang evening news reporter didn't find any parasites visible to the naked eye.

According to Zhejiang Aquatic Products Circulation and Processing Association, most of the Monopterus albus in Hangzhou market came from Hunan, Anhui and other places, and a few came from Huzhou and Jiaxing in our province. The number of jaw nematodes in wild Monopterus albus is definitely more than that in cultivated rice, but most of the time it needs to be seen under a microscope.

Research by the Institute of Parasitology of Zhejiang Academy of Medical Sciences also found that at a high temperature above 70℃, heating for 4~5 minutes can eliminate the jaw nematodes in Monopterus albus. For ordinary families, Ma 'an suggested cooking as thoroughly as possible. "After high-temperature cooking, these parasites will be killed, so don't worry too much."

Ma An reminded that raw food is actually the main cause of disease. Traveling to Southeast Asia and Guangdong and Guangxi, tourists like to eat raw fish, frozen eel slices and so on. , so the chance of being infected with E.coli will increase. Besides Monopterus albus, there are loach, snakehead, stickleback, catfish and eel. Therefore, these aquatic products must be cooked when eating.

What needs special reminder is that people in Hangzhou like to eat fried eel fillets, and restaurants like to fry them quickly. The jaw nematodes hidden in eel slices are probably not killed. However, curing, wine soaking, etc. , can't successfully kill nematodes.
