There are leeches in spinach? ?

Leech is a cold-blooded annelid, which can grow and breed in the north and south of China. Reservoirs, ditches, paddy fields and lakes mainly living in fresh water are mostly ponds rich in organic matter or pollution-free rivers. The optimum temperature for growth is 10-40℃, when it is lower than 3℃ in the north, it will enter a dormant period in the soil, and it will sting when it is higher than 8℃ in March-April of the following year. However, when water spinach matures, it is summer and generally grows in soil with sufficient water. The growth climate and environment of water spinach are also very suitable for leeches. So it is not surprising that many people report finding leeches in the spinach they bought. In fact, many plants and vegetables in paddy fields are easy to get leeches in summer, but other vegetables are easier to clean. Leeches are often found in water spinach because the stems are hollow and not easy to clean.

Leeches have suckers on their heads.

Eating leeches by mistake can be a parasite?

People have a fear of leeches, mainly because of their extraordinary blood-sucking ability. After being bitten by them, they often bleed because of the secretion of hemolysin, so there are often articles that list them among the most horrible animals in 10.

Leeches are not cute animals.

First of all, there is a certain deviation in the statement that leeches will parasitize in the human body. After all, leeches are not parasites, but they are often mistaken for parasites by some people because they have suckers at the head and tail, which can be adsorbed in the human body and suck human blood, which may cause some symptoms or organ damage. Leeches generally do not actively enter the human body, even if they are attached to the human skin. Those who say that leeches can enter the human body through the skin are also nonsense. Leeches generally enter the human body through the cavity connected with the outside world, so eating by mistake has become an important way for leeches to enter the human body.

Generally, the temperature is very high when cooking. At such a high temperature, even the tenacious leech will die soon. Moreover, leech itself is also a kind of traditional Chinese medicine, so even if leech is eaten by mistake, it will not have much impact on people's health. If they accidentally eat leeches that are not killed, they will enter the stomach and gastric juice. Therefore, it is unscientific to say that leeches are parasitic in human body through digestive tract. If you are worried that there are leeches in the dishes you buy, you can soak them in salt water for a while, so that the leeches that are not easy to see with the naked eye can leave the leaves and float on the water.

In this way, leeches are not as scary as everyone thinks. Some experts pointed out that leeches may still be parasitic in the human body and may cause damage to human organs. However, the environment in the digestive tract is extremely unfavorable to the growth of leeches, and leeches cannot survive under such conditions. Therefore, you don't have to be careful with food.

Because of its medicinal value, leech farming has become a way for many people to make money.
