Can crabs frozen to death in the refrigerator be eaten?
It depends on the specific situation.
1, If you buy live crabs and freeze them in the freezer, you can still eat them within 1 day after death, because the temperature in the freezer is between 3-5 degrees, which can slow down the growth of bacteria and decompose crab protein, and prolong the edible time of crabs.
2. If the crab died in the refrigerator for more than two days, it is recommended not to eat it, because the refrigerator can slow down the bacterial reproduction, but it cannot be completely inhibited. At this time, crabs may have multiplied a lot of bacteria, produced some histamine toxins, and deteriorated, which is not conducive to health after eating.
3. If the crab is frozen to death in the frozen layer of the refrigerator, it can be eaten and stored for one month without power failure.

The ability to preserve food is much weaker than that of professional cold storage. It is generally recommended to keep fresh food for no more than two months.
2. In addition, after half a year, there may be a power outage in the middle without knowing it, and there is no guarantee that the crab has deteriorated, which may cause harm to health after eating.

How to deal with frozen crabs?
1, cold water thawing
Frozen crabs are thawed by cold water, and the thawed basin of frozen crabs is brought to a place with temperature, so that the thawed is faster. For quick-frozen foods such as aquatic products and fresh meat, they should be moved from the freezer to the freezer (1℃-10℃). The food should be moved several hours to one day in advance (depending on the size of the food).
2. Thaw with salt water
If it is too late to put it in the refrigerator, the crab can be completely thawed in salt water. This is because salt water can accelerate the melting of ice without breeding bacteria. Tap water is not suitable for thawing frozen meat.
3. Add vinegar to thaw
Vinegar can also accelerate the melting of ice. You can pick up crabs with chopsticks and soak them in vinegar mixed with water, which can also speed up the thawing of crabs.
4. Thaw in the microwave oven
When thawing in the microwave oven, you must use the lowest grade and gradually heat it. At first, heat it for about two minutes, and then determine the heating time according to the degree of thawing of crabs until it is completely thawed.
