Whether hairy crabs can still be eaten after they die in the refrigerator depends on the specific situation.
1. Dead crabs placed in the fresh-keeping layer cannot be eaten
The temperature in the fresh-keeping layer of the refrigerator is relatively high, which can preserve vegetables and fruits, but it cannot inhibit bacteria very well. At the same time, it has no strong inhibitory effect on the enzyme activity in the hairy crab itself. Therefore, after the hairy crab in the fresh-keeping layer dies, a large number of fungi will still grow, and some histamine substances will also be decomposed and released in the body. It is toxic and cannot be eaten.
2. Hairy crabs that have been frozen to death in the frozen layer can be eaten
The temperature of the frozen layer of the refrigerator is generally 0 degrees Celsius. This temperature is very strong on the activity of fungi and enzymes. Inhibitory, hairy crabs stored in this layer will be frozen quickly. Therefore, hairy crabs are frozen to death and will not have their own fungi in their bodies and will not produce toxins. This is also the main method for long-distance transportation of hairy crabs. You can eat it with confidence.
