1 Can hairy crabs be eaten after freezing?
Frozen hairy crabs are edible, but they should be quickly frozen with special equipment.
Household refrigerators are only routinely frozen, which will lead to changes in the texture and flavor of hairy crabs.

At the same time, the characteristic flavor of hairy crabs will be weakened, and the bad flavors such as ammonia smell and fishy smell will be aggravated, so it is not recommended to freeze hairy crabs in domestic refrigerators.

Can cooked crabs be eaten after being frozen for 2 months?
I suggest you stop eating.
Cooked crabs are only temporarily refrigerated, not for storage. Generally, it must be eaten within 6-8 hours, otherwise it is not recommended to eat again.
Household refrigerators are not freezers, but only slow down the activities of microorganisms. Although cooked crabs kill microorganisms at high temperature, histidine in cooked crab meat will still be decomposed by microorganisms.
