Whether it is edible in the refrigerator depends on which layer it is placed on. If it is placed in the refrigerator, it is best not to eat it, because seafood that has been left overnight will breed certain toxic substances, and those who eat it will suffer from diarrhea. Severe cases may lead to poisoning. If placed in the freezer, you can eat it, but do not defrost it and steam it directly in a steamer, because steaming contains a certain amount of water to make the meat fresh and tender. But generally speaking, it’s better to cook and eat once and don’t have any leftovers.
