Now that it is summer, many people like to eat crayfish very much, but they never know that the environment is very bad during the growth of crayfish, and the processing process may not meet the hygiene standards. If it is not properly made, eating crayfish is likely to be accompanied by certain safety risks.
Before this, many professional doctors have said that when eating crayfish, we must pay attention to removing the head, because the head is not properly cleaned, and eating the head will have potential safety hazards to a great extent. This is all because the head cannot be thoroughly cleaned, and the whole body circulation and breathing system of crayfish are all near the head, and the lower body is only the part needed when crawling, so there are many harmful substances in the head of crayfish, and a large number of toxins in crayfish will be concentrated in the head if it is not handled properly.
Therefore, the head of crayfish is very dirty, and there are a lot of harmful substances, which is why when we pull off the head of crayfish, we will see the black part, but there is nothing in the body part. To sum up, when you eat crayfish, you must be careful not to eat the shrimp head, and it is best not to eat the black part of the head and the body. This is for your health. It is the season to eat crayfish, and everyone must pay attention to hygiene.
