Generally speaking, the shrimp thread of crayfish will not cause any substantial harm to human body, and it can be eaten, because the shrimp thread is only the digestive system of shrimp, which mainly contains things that have not been digested and absorbed in the shrimp body, and the harm after eating is not great, and crayfish will generally be cooked at high temperature, which can kill some bacteria.

However, the smell of crayfish and shrimp line is relatively strong, and sometimes it is mixed with some sediment and pebbles, which is easy to affect eating, so it is generally recommended to remove it.
