The snail eats the hard meat (the head and feet of the snail) on the upper part of the front screw mouth, which is edible snail meat. A piece of screw mouth is hard and tough meat. Remember, the hardest piece of meat.

However, some soft parts of the tail at the back are intestines, which are areas where excreta and internal organs are concentrated. This part is easy to parasitize some harmful substances and parasites, and it is dirty, so it is not recommended to eat.

inedible parts:

1. The tail of the snail, that is, the butt, is its internal organs, which are dirty. Generally, parasitic bacteria are in that place, and sometimes there are many snail eggs, which are also the excreta of the snail. Not recommended, and the taste is not good. It's best to cut it off when cleaning.

2. The tail of river snail is excrement, which is easy to be absorbed on the digestive tract wall after eating, difficult to digest and easy to cause intestinal discomfort.

method of treating the snail:

1. When treating the snail, first drop a few drops of cooking oil into the water of the snail and let it stand for 2-3 days, and change the water once or twice in the middle, so that the sediment in the snail will be basically discharged, and then wash the shell of the snail and break off the bottom, that is, the most pointed place, with pliers. Although this is very troublesome, it is necessary for health and hygiene.

2. After the treatment, clean it again, put it in a deep-mouth plate and add water. The two plates are interlocked and shaken back and forth, so that the sediment and impurities in the snail can be discharged. Do this for two or three times, and the water that comes out is clear water, which is clean.
