Hello, here is the query for you:

If the death time is short and the meat quality has not deteriorated, it is generally edible. If the time is too long, it is recommended not to eat it.

Whether a dead crab can be eaten after being steamed depends on the specific situation. If it has not been dead for a long time and the meat has not deteriorated, generally it can be eaten after being steamed. However, if the crab is dead, If it has been left for too long and has deteriorated to a certain extent, it is not recommended to eat it.

If the meat of dead crabs has deteriorated, it may produce a large amount of bacteria, such as aflatoxin. Even if it is cooked at high temperature, the bacteria will not be completely eliminated, and abdominal pain may occur after eating it. , diarrhea, vomiting and other uncomfortable symptoms.

Try to eat fresh crabs in daily life. People who are allergic to crabs are advised not to eat crabs.

If you have symptoms of discomfort after eating steamed dead crabs, it is recommended to go to the hospital for examination and treatment in time.

I hope my answer can help you, and I wish you a happy life.
