Wild crayfish are dirty, because these crayfish basically live in some stinking ditches. And these places can be said that the environment is relatively poor. The bought crayfish should be kept for a few days and replaced regularly every day to let the dirty things in the crayfish be discharged. But as long as the head is removed and the shrimp line is eaten, there is no problem at all.

The living environment of artificially cultured crayfish is better, and the requirements for water quality are still very high. It will not be raised in polluted waters, and it has the advantages of fixed feeding time and regular disinfection, so the artificially cultured crayfish is relatively clean, but we still have to remove the head and shrimp line when eating. ?

When eating crayfish, whether it is wild or farmed, the dirtiest place is the head and internal organs. As long as the shrimp head and shrimp line are removed, there is basically no problem and it can be eaten normally. Wash it and brush it with a brush. Wash it several times. Lobster can be used as the second intermediate host of paragonimiasis, but paragonimiasis is afraid of high temperature, and it will die at 70 degrees 10. As long as you don't eat raw or undercooked lobster, the possibility of shrimp contracting paragonimiasis is very small.
