1. Do crayfish use shrimp line?
Crayfish should go to shrimp line, because shrimp line is the excretory organ of crayfish, which contains a lot of shrimp excrement and bacteria, which is harmful to human body after eating, and crayfish without shrimp line has poor taste and bitter taste affects appetite, so crayfish should go to remove shrimp line.

Third, the precautions for eating lobster
1. Feed crayfish with clean water before processing at home: feed crayfish with clean water for about 24 hours before processing, let the lobster spit out metabolites, then brush the lobster with a brush to remove shrimp lines containing a lot of feces and bacteria.
2. Don't eat shrimp heads with accumulated toxin pathogens: the head of crayfish is the place where the toxins are absorbed and processed the most, and many pathogens and parasites are gathered, so it is not appropriate to eat too much. At the same time, crayfish belong to high purine aquatic products.
3. Dead shrimp is not edible: crayfish is rich in histamine acid. Once crayfish die, its histamine acid will be decomposed into histamine substances harmful to human body by bacteria. At the same time, the intestines and stomach of shrimp contain pathogenic bacteria and toxic substances, which are easy to rot and deteriorate after death. The longer the shrimp dies, the more toxins it has, and it will be poisoned if eaten.
