Are there any parasites in the snail?

Although the snail is delicious, it contains parasites, no matter how you wash it, you can't wash it clean, so you must cook it when eating, so you won't get parasitic diseases, but I suggest you eat it once in a while, and don't eat too much. Some parasites in snails are as follows:

1. Schistosoma japonicum

Schistosoma japonicum, also known as Schistosoma japonicum, is mainly parasitic in the veins of flat animals. in general, the larvae grow parasitically in snails and enter the body through the skin or mouth when they mature. Parasitic growth in the human body, the young eggs will pass through the vein wall into the bladder, and then excreted with the urine.

2. Angiostrongylus

Angiostrongylus is mainly parasitic in snails and snails, and then uses freshwater fish, freshwater shrimp and crabs as transfer hosts. If people eat it, they will parasitize into the human body. This parasite is very common and can occur in almost tropical or subtropical areas. Taiwan is an endemic area.

3. Fasciola hepatica

Fasciola hepatica is mainly parasitic in the liver or bile duct of herbivorous animals such as sheep and cattle. The eggs excreted by the parasites in the bile duct will be excreted out of the body with the bile and fall into the water, and then develop into miracidia at a suitable temperature, and finally parasitize on the snails.

4. Paragonimiasis

Paragonimus westermani, also known as paragonimus westermani, is the most common and harmful worm, which mainly enters people's lungs, abdomen, brain and other parts, and then causes blood sputum, cough, epilepsy and other diseases. Generally speaking, the first intermediate host is Sichuan snail, and the second intermediate host is brook crab, oratosquilla and so on. If people eat these undercooked food, it will cause infection.

The above is the introduction of how to wash snails and parasites in the body. I hope it will be helpful to you.
