Can you eat a crab after it's dead?

Generally, if a crab has just died and has been properly stored, it is usually safe to eat. However, if the crab has been dead for a long time and improperly stored, it is not recommended for consumption. The details are as follows:

If the crab has only recently died and has been stored correctly, bacterial growth can be effectively prevented. After being thoroughly cooked at high temperatures, it is generally safe to consume. However, before eating, one should check that the crab has no unusual odor or discoloration to ensure food safety.

If the crab has been dead for an extended period and stored improperly—such as being left at room temperature for a long time without proper refrigeration or freezing, or kept in unhygienic conditions—it is highly susceptible to bacterial contamination. In such cases, consumption is not advised.

It is recommended to select fresh, live crabs when purchasing and consuming. When cooking crabs, ensure they are thoroughly heated until fully cooked to eliminate potential bacteria and parasites, thereby protecting your health.
