Aquatic edible species have parasites in their bodies more or less. But after reasonable cooking, you can completely avoid risks. According to relevant research and test reports, there are many moving oval parasitic eggs in crayfish after ultrasonic cleaning, but when we keep heating at 50 degrees Celsius and high temperature for ten minutes or more, these parasitic eggs can disappear. Therefore, we must eat cooked crayfish, or we will be threatened with parasitic diseases. Therefore, if we eat it raw, or if we don't cook it, it will easily lead to parasitic diseases and so on.

Shrimp head is the place where toxins are absorbed and treated the most, and the part where pathogens and parasites are most likely to accumulate. The gills and viscera of the head are the main gathering places for pollutants such as heavy metals and parasites. It is suggested that when you eat crayfish, you should remove the head and the yellow part of shrimp, and there will be few heavy metals and parasites in the tail, even if there are any, and there is little possibility of poisoning. Special emphasis: be sure to eat well-done. Uncooked crayfish may contain paragonimiasis in the body, and people will be infected if they eat it. However, this kind of harm can be prevented. As long as it is cooked thoroughly, it can easily kill parasites. Cooking time should be sufficient, not less than 20 minutes. In order to make lobster meat tender, save raw materials and economic costs, many shops outside have insufficient cooking time, which has environmental health and safety risks. In the case of eating lobster, if it is found that the small tail of crayfish is straight, then this kind of crayfish is dead shrimp, so don't eat it. If it is bent and curled up, it means that it is live shrimp, edible and has certain nutrients.

The content of protein in crayfish is high, and the meat is soft and easy to digest, which is an excellent food for people who are weak and need to be nursed back to health after illness. Shrimp meat is also rich in magnesium, zinc, iodine, selenium, etc. Magnesium plays an important role in regulating heart activity and protecting the cardiovascular system. It can reduce the cholesterol content in blood, prevent arteriosclerosis, and dilate coronary arteries, which is conducive to preventing hypertension and myocardial infarction.
