When it comes to parasite infection, many people know that eating undercooked animal meat can lead to parasite infection;
Every year, there are many people who are infected with parasites due to eating raw shrimp, fish, crabs, snails and other aquatic products.
But many people don't know that eating certain kinds of vegetables raw can also be infected with parasites!

What's going on? There are a few possible reasons.
One is that parasites and vegetables live in the same environment, and parasites or eggs are attached to vegetables.
Second, vegetables are polluted by parasites or eggs in the process of fertilization, irrigation, and pesticide sprinkling;
In particular, vegetables irrigated with human and animal manure are highly susceptible to contamination by parasites and eggs.
Third, in the process of storage and transportation, vegetables are also easy to be infected with parasites on other vegetables due to collisions with other vegetables.
Vegetables with parasites or eggs attached to them should be rinsed with water before eating, and it is best to cook them before eating.
Let's take a look at five vegetables that are prone to parasites or eggs!
These 4 common vegetables are prone to parasites
Water chestnuts are also called water chestnuts, the taste is crisp and refreshing, the taste is sweet, you can cook and make desserts, many people from snacks to large.
Water chestnut is refreshing and delicious, and can be eaten both as a vegetable and as a traditional Chinese medicine.
It is a high-carb, high-protein, high-water, low-calorie vegetable, and is often used as a diet food.
Lotus root is a common ingredient on our table, which can be stir-fried, stewed, and steamed.
The common feature of the above four vegetables is that they are all common aquatic plants that grow in moist underground swamps or paddy fields.

Fresh water chestnuts and water chestnuts have a short shelf life, and because they are crisp, sweet, and juicy when eaten raw;
Therefore, many people often choose raw food as soon as they are picked or purchased.
So the problem is, raw water chestnuts, water chestnuts, callus white, and lotus root will all have the risk of infection with Fasciola brucei!
The ultimate host of Fasciola brucei is mammals such as pigs, and the eggs are excreted through pig feces, and if the eggs contaminate the water source, they can develop into larvae in the water;
After the hairy larvae encounter the intermediate host snail, they develop into cercariae in the snail, and the cercariae escape from the snail and attach to aquatic plants such as water chestnut, water chestnut, callus white, lotus root, etc., forming cysts on the surface.

After the cysts of Fasciolia brucei are accidentally ingested into the human body, the cyst wall is digested by gastric juice, and the larvae will parasitize in the small intestine, and can develop into adult worms after 1~3 months, resulting in fascioliasis;
Inflammation, bleeding, ulcers or abscesses of the intestinal mucosa, resulting in abdominal pain, diarrhea, loss of appetite and other symptoms in infected patients;
In the later stage, edema and ascites may occur, and in severe cases, malnutrition, affecting growth and development, and even death.
Infection can also affect physical and mental development in children.
Therefore, it is recommended not to eat water chestnuts, water chestnuts, water chestnuts, lotus roots, and do not gnaw the skin with your teeth.
Someone asked, is it okay to soak it in salt water?
Salt water does not kill Fasciola brucei, and the best way to kill the insecticide is by high temperatures.
Because Brydei ginger cysts are not resistant to high temperatures, they will die if boiled in boiling water for 1 minute.
Therefore, it is best to wash water chestnuts thoroughly before eating, peel them, and cook them in boiling water for more than 1 minute before eating.
Water chestnut can also be eaten by peeling the shell after steaming or cooking, or boiling porridge, or crushed into puree to make water chestnut cake.
Water celery with fasciola hepatica
The celery we often buy in the vegetable market is mainly dry celery that grows in the dry land of the north, and there is also a kind of celery family called water celery;
Water celery grows mainly in southern river ditches, paddy fields, or in moist, soft, fertile soils.
A large fluke belonging to the same family as Fasciola brucei is called Fasciola hepatica.
Fasciola hepatica is an adult worm that lives in the bile ducts of cattle, sheep and other mammals;
However, their intermediate hosts include snails and aquatic plants, and it is possible that the cysts of fasciola hepatic may attach to the surface of water celery;
If we pick water celery and eat it without washing it or cooking it, we may be infected with Fasciola hepatica.

After being ingested by the human body, fasciolia hepatica cysts will invade the liver from the abdominal cavity through the small intestine and transfer to the bile ducts, and can also enter the bile ducts through mesenteric veins or lymphatic vessels, causing fascioliasis hepatic.
Fasciola hepatica infection can cause liver diseases such as chronic cirrhosis, liver fibrosis, and portal hypertension.
These conditions can cause symptoms such as jaundice, bloating, diarrhea, nausea, vomiting, and weight loss, and can be especially harmful to children.
Fasciola hepatica can also stay in various related organs such as lungs, brain, orbits, subcutaneous and other places in ectopic parasitism during migration, causing great harm.
They can parasitize in the human body for up to 12~13 years.
Therefore, before eating water celery, we must clean the soil on the surface, and we must fry it before eating.
How to wash and cook vegetables correctly?
Vegetables that have been bought with a lot of dirt or look very clean to the naked eye should be carefully rinsed several times with running water before eating, and it is recommended to wash them repeatedly.

Because it is inevitable that there will be parasites and eggs attached to these vegetables, and they cannot be seen clearly or invisible with the naked eye, but if they are eaten into the human body, it will be a big trouble.
Rinse repeatedly with running water to wash away most of the parasites and eggs.
Summer is coming, and it is the season to eat water chestnuts, water chestnuts, water chestnuts, lotus roots, water celery and other aquatic plants, but we must not eat them raw.
These parasites are basically afraid of high temperatures, so they must be fried, cooked, and steamed before eating, so that there is no need to worry about the risk of parasite infection.
