Crabs can be kept in the refrigerator for about 3 days. After all, crabs are living things. Putting crabs in the refrigerator is to delay the eating time of crabs properly. Putting crabs in the refrigerator can survive for about 3 days, which is already a better storage method.

Tie the crab's legs and feet, put them in a foam box and add water. The foam box can be frozen in the freezer of the refrigerator. Just take it out and thaw it when you want to eat crabs, so that preserving crabs can ensure the freshness of crabs to the greatest extent.

If you don't eat it right away, please don't wash it with water, or the crab will die. If the indoor temperature does not exceed 15℃, there is no need to put the refrigerator. Under normal circumstances, it can be stored for 5-7 days, but the crab will lose weight if it is stored for too long, and the taste will not be affected if it is eaten within 3 days.

Dead crabs can't be eaten;

Dead crabs produce a lot of histamine. Histamine poisoning occurs when people eat dead crabs. Because histamine is an allergic poison, also known as allergic food poisoning. People who are allergic to histamine will react even with a bite.

For example, after eating dead crab 10 minutes to 3 hours, symptoms such as flushing on cheeks, flushing on chest and whole body skin, conjunctival congestion, headache, dizziness, chest tightness, general fatigue and irritability will appear.

Never eat dead crabs. Another important cause of poisoning is bacterial infection. Generally speaking, the living environment of wild crabs is not as good as that of artificial crabs and marine crabs. Once the crab dies, the bacteria inside and outside the crab will multiply, decompose the crab meat and produce toxins. Relatively speaking, the risk of bacterial infection is high, and people are more prone to bacterial infection after eating.
