Yes, first of all, you can use high temperature to kill the parasites in the snails, you can put the snails into boiling water for a period of time, and the length of time is grasped in more than five minutes, so that the parasites can be killed. Most parasites are not sensitive to chemicals, but are not resistant to drying and high temperatures, and boiling water will kill them in a few seconds. One hundred percent of the freshwater fish we normally eat are host to parasites, but as long as they are cooked thoroughly. Second, will buy the snails with pomelo leaves or lemon slices, lightly salted water soaked overnight, so that the next day, the snails will spit out some unclean things, but also spit out part of the parasites, at this time the snails will be fished out and washed can be.

Extended information

The snail refers to the mollusks of the family of snails, belonging to the mollusc family Gastropoda Gastropoda Pregillae subclass Tian snail family. The snail is distributed in most parts of the country. It can be caught in summer and fall. In freshwater, there are Chinese round snails, Chinese round snails and so on.

The snail is a mollusk. The body is divided into three parts: the head, the feet, the visceral sac, etc. On the head there are mouth, eyes, antennae and other sensory organs. There is a shell outside the body. The foot muscles of the snail are well developed and located on the ventral surface of the body. The diaphragm on the bottom of the foot is called the operculum, which resembles a round lid. When in trouble or in need of rest, the snail shrinks its body in the shell and, through the muscle contraction of the foot, covers the shell tightly with the operculum. The snail is edible, and the edible part is mainly its fleshy foot. The field snail is found in most parts of the country. It can be caught in summer and fall. The Chinese round snail and the Chinese round snail are common in freshwater.

The snail usually grows in the pond, if the water quality is not good, it is easy to be contaminated, especially when eating if the snail inside the stool is not discharged, there are a lot of parasites, such as the nail dowel is the host of schistosomiasis. Therefore, it is best to buy river snails or snails to eat, less snails in the pond, buy back a bucket of water to put the snail to raise a few days, change the water once a day, so that the snail to the stool clean, cook the snail to boil through to kill the parasites. It's best not to eat grilled conch, because if it's not cooked, it's easy to get infected with liver fluke.

The field snail is dioecious.

The way to distinguish between male and female snails is mainly based on the shape of their right antennae. The male snail's right antennae are curved inward to the right (the curved part is the male genitalia), and in addition, the female snail is large and round, while the male snail is small and long. The snail is an ovoviviparous animal with a unique reproductive pattern, in which the embryonic development of the snail and the development of the young snail are completed within the mother's body. From the fertilized egg to the baby snail, it takes about one year of gestation in the mother's body. The snail is a batch spawning process, which starts in March-April every year, and at the same time when the baby snails are produced, the female and male parent snails are mated and fertilized, and at the same time the baby snails to be produced in the following year are conceived in the mother's body. A female snail produces about 100 to 150 young snails throughout the year
