Crab steamed out with a turquoise minced on it? Why?

Crabs that are steamed with a blue-green end on them may have the following reasons:

1.Crabs contain parasites in their bodies. If the parasite enters the crab and parasits in the crab's bile duct, it will cause the crab's digestive glands and mucous membranes to turn green, and after the bile flows out, the crab will be green when it is steamed out.

2.There is a problem with the quality of the feed that crabs eat on weekdays. When the crab eats it for a long time, a lot of feed residues remain in the crab's body, and the steamed crab will be green.

3.Crabs use too much veterinary medicine. If the crab suffers from a disease before it is born, when it uses too much veterinary medicine, there will be drug residues in the crab's organs, resulting in a green color of the steamed crab.

The above are a few common reasons, and it is recommended that you try to buy fresh crabs and eat regular feed. Take care to check the quality and safety of ingredients before cooking.
