Precautions for eating crayfish
1. Crayfish contains a lot of bacteria and parasites, and a lot of heavy metals, but they are basically in the head. So when you eat it, you must take off your head! Don't try to save money and eat your head together. In view of the fact that the crawfish sold in most restaurants for convenience are basically headless, it is necessary to remove the head from the crawfish before eating.
2. The shrimp line must be removed. This part is the second dirty place next to the head. Many restaurants do not remove the shrimp line in order to save money, so it is suggested that you buy it home as much as possible to make your own food.
3. Clean crayfish carefully and carefully. The crayfish sold outside can't be washed carefully by the businessmen in order to save trouble, and many unscrupulous businesses will use the shrimp washing powder to clean the crayfish, and the residual shrimp washing powder is quite harmful.
4. The last point is that the cooking time should be enough, not less than 20 minutes. In order to save fuel cost and time cost, many outside businesses do not have enough cooking time, which is a potential health and safety hazard.
5. Shrimp should not be eaten with some fruits. Shrimp is rich in protein, calcium and other nutrients. If they are equal to fruits containing tannic acid, such as grape, pomegranate, hawthorn and persimmon, it will not only reduce the nutritional value of protein, but also form insoluble combination of tannic acid and calcium ion to stimulate stomach and intestines, cause human discomfort, vomiting, dizziness, nausea, abdominal pain and diarrhea and other symptoms. Seafood should be eaten with these fruits at least 2 hours apart.
