Dead crabs can't be eaten. Crabs like to eat dead fish, dead shrimp and other rotten animal carcasses in the water, and certain bacteria will accumulate in the crab's body. In particular, river crabs mostly grow in dirty river ponds, and there are a large number of germs inside and outside the crabs.

Therefore, raw crabs cannot be eaten, and they must be washed, steamed and cooked thoroughly before they can be eaten with confidence.

Crabs often carry lung flukes and Vibrio parahaemolyticus, which can cause paraflukes or bacterial food poisoning if left unsterilized or killed, and can be life-threatening in severe cases. The saying that crabs are eaten raw and shrimp eaten alive is unscientific.
5.Do not consume excessive amounts

Crabs are rich in protein, and persimmons contain more tannin and pectin. When crabs and persimmons are eaten together, the protein is combined with tannins, which is easy to precipitate and solidify into an indigestible substance. Because tannin has an astringent effect, it can also inhibit the secretion of digestive juices, causing coagulated substances to remain in the intestine for fermentation, causing vomiting.
