Why can't you eat dead crabs?
Crabs mainly live on rotten dead fish and shrimp in the water. In addition, crabs breathe through gills, and substances such as sludge and weeds often stay in gills. Therefore, there are many bacteria in the body. When crabs are alive, bacteria can be excreted with their metabolism in the body. Once they die, the bacteria in the body will multiply and decompose crab meat. Some bacteria will produce toxins, which are harmful to the body.

How to deal with crabs to reduce bacteria
1. Wash crabs, especially crab shells, which often contain sediment. Wash it with cold water and peel off the inedible parts as much as possible. This part of bacteria is the easiest to breed.
When cooking crabs, be sure to cook them thoroughly. When the whole crab is heated, the heat is not easy to penetrate. In addition, if the crab shell is thick and the crab is not cooked, the Escherichia coli hiding in the gills and shell corners should not be killed. These bacteria are easy to cause gastrointestinal discomfort. Generally, it takes 15-20 minutes to steam on high fire.
