Whether hairy crabs can be eaten after freezing depends on the time of freezing and the freshness of hairy crabs.

if the hairy crabs have just frozen to death, and they are frozen to death under cold storage conditions, they can generally be eaten, because the hairy crabs under cold storage conditions are easier to preserve and not easy to deteriorate. However, if hairy crabs freeze to death for a long time, or freeze to death under freezing conditions, it is not recommended to eat them. Because hairy crabs under freezing conditions are easy to deteriorate, and the longer they freeze to death, the greater the possibility of deterioration. Deteriorated hairy crabs may produce harmful bacteria, which will do harm to human health.

In addition, it should be noted that hairy crabs are a kind of high-protein food, which is easy to breed bacteria, so they must be fully heated and cooked before eating to avoid food poisoning. If you are not sure whether hairy crabs are fresh or not, it is best not to eat them, so as not to cause adverse effects on your body.

Tips for purchasing hairy crabs

1. Look at the appearance: the shell of fresh hairy crabs is bluish gray, smooth and shiny, the abdomen is white and clean, the feet are long and yellow, and the abdomen and the inside of the claws are milky white. If the shell is black and blue, the abdomen is dark and the foot hair falls off, it means that the hairy crabs are not fresh.

2. Look at the navel: The navel of hairy crabs is a very important indicator. The navel should be round, full, slightly convex and light red or khaki in color. If the navel is black or crimson, it means that the hairy crab may be dead or about to die.

3. Look at the crab claws: The crab claws of hairy crabs should be strong, with dense hairs on the inside and golden yellow or deep yellow in color. If the hairs on the inside of the crab claw are sparse and the color is black or light, it indicates that the quality of the hairy crabs may be poor.

4. Look at the weight: the heavier the hairy crabs of the same size, the better, because the heavier the weight, the fuller the meat.
