1. Crab gills belong to the respiratory organs of crabs. When crabs breathe in water, they will filter out some pollutants. Therefore, crab gills are contaminated parts and cannot be eaten. Pay attention to removing crabs when processing them.

2. The stomach of crab belongs to the digestive organ of crab. When eating, crabs will ingest more toxic and harmful substances such as sediment, and their stomachs need to be removed during processing.

3. Crab intestines also belong to the digestive organs of crabs. Crab intestines contain crab excrement, which contains more pollutants than crab stomachs, and is even more unsanitary.
