Introduction
Under normal circumstances, the abdominal part of king crab is not recommended for consumption. When preparing king crab, this abdominal section should be completely removed and properly discarded to prevent its fluids from contaminating other edible parts. Before eating, thoroughly rinse the crab body with clean water to remove surface impurities, and ensure the crab is fully cooked, especially in thicker sections such as the legs and claws.
Generally, it is not recommended to eat the abdominal part of king crab. The detailed explanation is as follows:
The abdominal area of king crab contains very little meat and is a concentrated region of internal organs, which may accumulate heavy metals, parasites, and metabolic waste. Consuming this part could increase the body's metabolic burden. Additionally, the tissue in this area is delicate and prone to bacterial growth; if improperly handled or not thoroughly cooked, it may cause gastrointestinal discomfort such as nausea and diarrhea. Moreover, some king crab abdomens may contain residual roe or secretions, resulting in a fishy, greasy taste with poor palatability and little culinary value. Therefore, this part should not be eaten.
When preparing king crab, the abdominal section should be completely removed and properly discarded to prevent its fluids from contaminating other edible parts. Before consumption, the crab body should be thoroughly rinsed with clean water to remove surface impurities. During cooking, ensure that the crab is fully cooked through, especially thick sections like the legs and claws. King crab should be processed and cooked immediately. If not consumed entirely in one sitting, the edible portions should be sealed and refrigerated, and consumed within 24 hours. Prior to eating again, they must be thoroughly reheated to ensure food safety.
