Whether cooked crabs can still be eaten after being frozen for 6 months depends on the specific situation. If you buy vacuum-packed cooked frozen crabs on the market, they have generally undergone strict sterilization, disinfection and other professional treatments. Generally, it can continue to be consumed as long as it has not expired and the packaging does not leak, and it will not have any adverse effects on the body. If you cook crabs for yourself, you won’t be able to eat them after 6 months of freezing them.

If self-cooked crabs are frozen for 6 months, the freezing time is too long, and the strict sterilization effect is often not achieved when they are self-frozen. Moreover, when the freezer layer of the refrigerator is opened and closed, the crabs may thaw slightly, and crabs that are not vacuum packed may harbor bacteria. In this case, crabs are prone to spoilage. After thawing, discoloration, stickiness, abnormal rancidity, etc. may occur, and a large number of bacteria and other pathogenic microorganisms may breed. After consumption, it can cause food poisoning, with symptoms such as fever, dizziness, nausea, vomiting, abdominal pain, and diarrhea.

In addition, even if cooked crabs do not deteriorate after being frozen for 6 months, a large amount of nutrients such as protein and amino acids will be lost, and the taste will be significantly reduced. Compared with fresh crab, the edible value is lower. Once defrosted, the crab needs to be heated thoroughly in a steamer before eating.

It is recommended that the general public cook crabs once a day and avoid storing cooked crabs for a long time. If there is a need for preservation, you can put the cooked crabs into a clean fresh-keeping bag or box, seal them well, and then freeze them in the refrigerator to avoid repeated freezing and thawing, and try to defrost them within a month. If stored in the refrigerator, it is recommended to eat as soon as possible with a good seal.
