These parts of crabs cannot be eaten

Crabs are a favorite of many people because of their delicious taste and rich nutrition. Now is the season when orange crabs are fat. Whether it is home cooking or dining out, crabs have become a regular guest on the table. However, did you know that not all parts of crabs are suitable for consumption? These three parts cannot be eaten!

Crab gills

Open the crab shell and you will see soft, grayish-white things like caterpillars on both sides of the crab body. These are crab gills. Crab gills are the crab's respiratory organs, and are mainly responsible for filtering impurities and harmful substances in the water. Therefore, harmful substances such as bacteria, parasites, and heavy metals are easily accumulated in crab gills. If eaten carelessly, they may pose a threat to human health, such as causing diarrhea, abdominal pain, and other discomfort symptoms.

Crab stomach

At the top of the crab shell is a triangular bag covered with crab roe or crab paste, which is the crab stomach. The crab stomach is part of the crab's digestive system and may contain various impurities, waste and undigested food ingested by the crab. In addition, the digestive juice in the crab stomach may also contain some acidic substances, which may irritate and cause discomfort to the human stomach.

Crab intestines

Open the small cover on the crab's abdomen and you will find a triangular area with black strips inside, which is the crab intestine. The crab intestine is the crab's digestive and excretory organ, which is full of digested food residues and harmful substances. Eating crab intestine may cause abdominal pain, diarrhea and other symptoms.

The crab heart is located between the crab roe and the black membrane. It is hexagonal and white. It is the power organ for the crab's blood circulation. It is rumored that the crab heart is extremely cold, but there is no evidence to support this statement. The crab heart can be eaten, but the taste is not very good.

In addition to the above parts, other parts of the crab, such as crab meat, crab roe (crab paste), etc., can be eaten after being thoroughly cooked. These parts are rich in protein, vitamins and various nutrients, which are beneficial to human health. However, since crabs may contain parasites, bacteria and other harmful substances, it is necessary to ensure that they are thoroughly cooked before eating. For people who are allergic to crabs, they should avoid eating crabs.
