Why do crabs need to be steamed and cooked to be eaten?

For the first time today, I bought crabs and cooked them myself. The recipe says that the crabs must be steamed and cooked. Why is this?

    Crabs often carry cysts of paragonimiasis and Vibrio parahaemolyticus. If not sterilized by high temperature, the paragonimiasis may cause lung damage after entering the human body. If a large amount of Vibrio parahaemolyticus invades the human body, infectious poisoning will occur, showing symptoms of intestinal inflammation, edema, and congestion. For this reason, the crab must be steamed and cooked thoroughly, sterilized and sterilized. Generally, it is better to open the pot and cook for more than 30 minutes.
