Snails can't eat their tails. Although there is little snail meat, not every part can be eaten. We usually eat a hard and tough piece of meat near the snail's mouth, and some soft parts near the bottom are the snail's internal organs. Because this part is easy to parasitize some harmful substances and parasites, plus it is dirty, we generally don't eat these.

Cleaning method of river snail:

Drop a few drops of cooking oil into the snail's water and let it stand for 2-3 days. Change the water 1-2 times in the middle to let the sediment in the snail basically drain away. Then wash the snail's shell and break off the bottom, that is, the most pointed place, with pliers. Although it is troublesome, it is necessary for health and hygiene. After the treatment, it is washed again, put into a deep mouth plate and added with water. The two plates are interlocked and shaken back and forth, so that the sediment and impurities in the snail are discharged. Do this for two or three times, and the water that comes out is clean and clean.
