Can dead crabs be eaten?
First of all, dead river crabs cannot be eaten
.
The crab grows in a freshwater environment and is suitable for microbial production.
There are many bacteria inside and outside the body.
Once it dies, the meat quality will deteriorate rapidly, and it is easy to produce a large amount of toxic histamine, which can cause allergic reactions in the human body; but the crab grows in salt content.
In the high seawater, the environment is special and there are relatively few bacteria inside and outside the body.
It is easy to die after being salvaged.
Dead sea crabs frozen in time and well-preserved are edible, but they cannot be stored for too long
