The 46-year-old Mr. Liu, a Guangdong native, stayed in Beijing to work after graduating from college, and a few days ago, went back home for a while because his father was hospitalized.
After returning to work in Beijing, he found that he always had inexplicable symptoms of weakness, loss of appetite and diarrhea, and at first thought it was caused by being too tired at work, so he didn't care. As a result, after 1 month, the symptoms did not abate, but also continued to have fever and chills.
That's when Liu went to the hospital for a checkup, and that checkup scared Mr. Liu. The doctor said his left liver had turned into a big pus ball and was almost hollowed out! Further examination revealed that Mr. Liu's liver was covered with a large number of eggs from liver flukes and that only surgery could be performed to remove most of the left side of the liver.
But why did Mr. Liu get infected with liver flukes? The company's main goal is to provide the best possible service to its customers. The doctor said that Mr. Liu was infected with liver fluke mostly caused by the habit of eating raw fish. The company's main goal is to provide the best possible service to its customers.

I. How terrible is it to be infected with liver fluke?

According to the Guangdong Department of Health, the infection rate of liver fluke in Guangdong province is 16.13%, and the estimated number of infected people is up to more than 5 million, accounting for about 50% of the country. Especially in the Pearl River Delta area, where eating raw fish is prevalent, the infection rate of the population is as high as 74.5%. With such a high rate of infection, is there any harm to the human body?
The liver fluke is a parasite and a Group I carcinogen recognized by the International Agency for Research on Cancer, and it can be found mainly in the bile ducts of the human liver.
In the early stages of infection, there are no obvious symptoms. After the liver fluke enters the body, the adult fluke moves around in the bile ducts, causing damage to the mucosa and epithelium of the bile ducts. The secretions and metabolites of the worms will be excreted in the bile ducts, and these excretions have certain carcinogenic effects, easily inducing gallstones, cholecystitis, jaundice, etc., and in serious cases, even bile duct cancer.
Long-term infection can also cause atrophy and degeneration of liver cells and abnormal proliferation of fibrous tissue around the portal area, which can lead to cirrhosis and liver cancer in later stages.

II. 5 kinds of food harbor a large number of parasites, must be eaten less

1. Fosu snail: Canton tube round nematode
Fosu snail is an invasive organism, its body is easy to parasitize Canton tube round nematode. A single foxglove snail may host more than 6,000 Guangzhou tubular nematode larvae, and people are easily infected after eating uncooked foxglove snails. Once the infection occurs, it can give a person a severe headache, nausea, fever, and coma, and can cause death in severe cases.
In general, it is recommended not to eat snails, but to cook them thoroughly if you must, and not to eat them half-cooked.
2. Water chestnuts, rhizomes: Brucella gingerbread
Mammals such as pigs are the final host of Brucella gingerbread trematode, its eggs will be discharged through the feces of pigs, and if the feces is discharged to the water source, the eggs will develop into caterpillars in the water; the caterpillars will develop into caecal larvae in the intermediate host snails, and the caecal larvae will be attached to the surface of aquatic plants to form cysts when they come out of the snail body, such as water chestnuts
If the larvae of the snail are not present, the cysts will be formed on the surface of aquatic plants, such as water chestnut, rhizome, lotus root and wild rice.
If you eat water chestnuts and rhizomes raw under such circumstances, you may allow the cysts to enter your body, and the larvae's cyst wall will be digested by gastric juice and then parasitize in the small intestine, which will develop into adult worms over 1-3 months, causing gingerbread disease.
After the onset of the disease, symptoms such as abdominal pain, diarrhea and loss of appetite may develop, which may cause severe ascites, malnutrition and even death in the later stages of the body.
Buccal ginger worms are intolerant of high temperatures and will die after a minute of high temperature cooking, so it is advisable to cook these types of foods first.
3. Eels: jaws nematode
The number of parasites on eels can reach as many as 15 species, and jaws nematode is one of the common ones. The eel's body will be full of nematodes, which can cause a series of abnormal symptoms and, in severe cases, organ perforation and bleeding.
4. Drunken shrimp and drunken crab: lung fluke
Freshwater shrimp and crabs are likely to have lung fluke inside them, and people are likely to be infected when they eat raw drunken shrimp and drunken crab. The infection can cause the body to experience symptoms such as coughing, coughing up blood, difficulty breathing, and if the parasite transfers to the brain, it can also cause epilepsy and paralysis to occur.
5. Raw pork: pig tapeworm
The most common parasite in pork is the pig tapeworm. If the pork happens to have a pig tapeworm in it, the person may be infected after eating it if it is not fully cooked or if the pork is eaten raw. There are usually no obvious symptoms in the initial stage of infection, but as the disease progresses, there will be a series of symptoms such as diarrhea, dizziness, and weight loss. It is parasitic in the brain and can cause epilepsy.

3. 4 things to do to keep parasitic infections away

Parasitic infections can pose a great health risk, and it is important to do these things to prevent them.
Most parasites are intolerant of high temperatures and can be killed when cooked thoroughly at high temperatures. Make sure to cook your food longer on a daily basis to ensure it is fully cooked.
Separate raw and cooked foods with separate cutting boards and knives to avoid possible parasites on raw foods from infecting cooked foods, and separate utensils for raw and cooked foods.
Water that has not been fully boiled may contain a large number of parasites and germs, especially water from ponds and rivers in the wild, which must be avoided.
Go to formal shopping malls or supermarkets for your daily food purchases. These places are relatively more formal and have stricter inspection for fresh food, so the chance of having problematic food is relatively low.
Parasites are very common in our lives, and many are hidden in our food. It is important to prevent parasitic infections in our daily lives by minimizing or not eating raw foods and by practicing good personal hygiene to reduce the risk of parasitic infections.
