Shrimp yellow, I suggest not eating it. Because crayfish head has many organs and high metal content, it is not suitable for eating. According to experts, the gill, liver, stomach and other organs of crayfish are all in the head, and food and water will pass through and stay in the head, so the heavy metals in the shrimp head are generally higher than those in the shrimp tail, and the shrimp yellow is the shrimp gonad, which is next to the liver and is easily polluted. Therefore, eat as little shrimp yellow as possible.
Shrimp yellow is rich in nutrition. Some people think it's a pity not to eat it. If you want to eat it, you should treat it, remove heavy metal factors and excreta. The purchased live shrimp should be fasted in clear water, and then eaten after 24 hours, so as to discharge the excreta from the shrimp head and reduce the amount of heavy metals, which can reduce the harm to the human body.
In addition to eating shrimp yellow, crayfish should also pay attention to the following matters:
1, edible crayfish, generally, the shrimp meat is soft and inelastic, with strong fishy smell and dark color, which may be dead shrimp, so it is necessary to pay attention to eating.

2. When buying crayfish, you should choose the one that is complete, the shell has not fallen off, the shell is clear, the meat is dense, the shrimp tail is flexible, clean and dry. When eating, rinse the shrimp, and it should be mixed with ginger and vinegar, which can relieve fishy smell, add freshness, reduce fever and cold, facilitate digestion, and also kill, sterilize and disinfect.
3. Self-made crayfish should be fed with clear water for 24 hours before processing, so that the shrimp can spit out metabolites, and the gut should be removed before eating.
4, shrimp head can not be eaten. Shrimp head absorbs and processes the most toxins, and it is easy to gather pathogens and parasites.
