If crabs freeze to death in the frozen layer, they can generally continue to eat. Because the temperature of the frozen layer is basically MINUS ten degrees Celsius, it can inhibit the growth of bacteria. Crabs generally do not produce bacteria and cannot secrete harmful substances such as histamine at low temperatures. However, thawing cannot occur in the middle, so as not to be invaded by microorganisms such as bacteria and lead to crab deterioration.

How long can frozen crabs be kept?

Crabs can be preserved for 3 months without taste deterioration if they are frozen quickly and not thawed halfway.

If the live crabs put into the frozen layer are kept at home, they must not be thawed halfway, otherwise the thawed crabs are very vulnerable to the invasion of microorganisms such as bacteria, which leads to their deterioration, especially the resistance of Paragonimus cysts in fresh water crabs is very strong, and even frozen dead crabs are prone to food poisoning. Therefore, in order to prevent thawing halfway, frozen crabs should be eaten as soon as possible, preferably within one month.
