Do the semi-finished products of the hotel kitchen refrigerator need to be labeled?

The catering part should be marked with raw cooked food, beverages, semi-finished products, etc. The upper layer of the refrigerator is a cold room, where you can put some food and drinks, fruits and the like, and the lower layer of the refrigerator is a freezing room, where you can put some raw or cooked meat and things that need to be frozen, such as frozen meat and steamed bread. Moreover, every floor should be labeled, on the one hand, for the convenience of searching, and on the other hand, for the sake of safety.
