Oysters are also called oysters or sea oysters. The internal organs of the oyster cannot be eaten. There is a piece of green stuff in the belly. This is the food that the oyster has eaten. It is unhygienic. It is best not to eat this part. If If you really want to eat it, it’s best to wash it and cook it before eating it.
Reason: Heavy metals and other pollutants are easily hidden in the viscera of oysters, and the content of heavy metals is the lowest in the muscle alone. Therefore, when eating the muscle part of oysters, first look at the color. The slightly blackened meat is mostly viscera. This part cannot be eaten because of the smell. If there is a strange smell, it means that the oysters are spoiled and should not be eaten anymore.
