Can I still eat a crab that died in the refrigerator?

Under normal circumstances, it is generally not recommended to consume crabs that have died in the refrigerator, to avoid potential health risks. Detailed explanations are as follows:

After a crab dies, bacteria in its body multiply rapidly, including harmful types such as Escherichia coli and Salmonella. Although refrigeration can slow the growth of some bacteria, it cannot completely prevent bacterial proliferation. As the time since death increases, bacterial counts continue to rise, potentially leading to spoilage and the production of harmful chemical substances.

Consuming dead crabs may cause food poisoning, with symptoms including nausea, abdominal pain, and fever. The toxins produced by these bacteria are often difficult to fully eliminate through high-temperature cooking. Even if thoroughly cooked, dead crabs may still contain residual toxins. Additionally, the nutritional value of the crab gradually deteriorates after death, and its texture and flavor also decline.

To ensure food safety and health, it is recommended to cook and consume only fresh, live crabs. If a crab has died in the refrigerator, it is advised to discard it and replace it with a new live crab. In daily life, attention should be paid to consuming fresh food sourced from reliable channels. Before consumption, ensure food is thoroughly cleaned and fully cooked to avoid undue gastrointestinal irritation, which may lead to symptoms such as bloating and abdominal pain.
