Can you eat crabs when they re dead? It s been in the fridge all the time

According to the living habits of crabs, it is not recommended to eat dead crabs. Crabs love to eat rotten food, and pathogenic bacteria and toxic substances accumulate in their bodies. Dead crabs can quickly grow a large number of bacteria in their bodies, so they should not be eaten, especially in hot weather.

There is also a histidine substance in the crab's body, histidine is easy to decompose, histamine and histamine-like substances can be produced under the action of decarboxylase, and the midgut gland will quickly fall apart after the crab dies, and the histidine and digestive enzymes in it will decompose the crab meat. So, the taste of dead crabs is weird. The crab itself is non-toxic, but after the crab dies, after the crab's shell is broken, the protein in the crab's body will breed bacteria, and the infected bacteria in its body will multiply, and the bacteria may produce toxins.

Dead crabs are likely to be poisonous. If the crab has not been dead for a long time, it can still be eaten if it is refrigerated, remember, it is refrigerated and not frozen, and the sea crab is better than the river crab, because the living environment of the river crab is poor, and there are more bacteria...

Generally speaking, the river crab can not be eaten if it is dead, and the sea crab can still be eaten if it is frozen just after it is dead, and the crab is generally preserved and then frozen after being cooked with salt, and do not drink raw water for 2 hours after eating the crab.

When the river crab dies, it can't be eaten.
