After this time, the crab will produce harmful substances to the human body, continue to eat may appear food poisoning hazards, so can not eat.

Can you eat crabs that are dead when you put them in the freezer 3 Dead crabs in the freezer layer can be eaten. Because the temperature of the freezing layer is relatively low, usually below zero, it can freeze the food, which has an inhibitory effect on bacteria and various enzymes. Although the crabs are frozen to death, they will not produce bacteria inside their bodies, and cannot secrete histamine under low temperature, so they can continue to be eaten. Generally speaking, crabs can be preserved for 3 months without losing their flavor if they are frozen and not thawed in the middle of the day. Note that the frozen layer into the live crab, must not be thawed in the middle of the phenomenon, otherwise thawed crab is very susceptible to invasion by bacteria and other microorganisms, resulting in its deterioration, especially freshwater crabs in the Schistosoma cysticercus resistance is very strong, even if it is a frozen dead crabs are also susceptible to food poisoning phenomenon, therefore, the general frozen crabs best to be consumed within a month as well.
