This chart may be used to help identify variations in pork quality.
The quality of fresh pork varies greatly. The quality levels shown below will appear differently to consumers, taste differently when cooked, and perform differently when converted to processed products. High-quality pork has a greater monetary value than low-quality pork. Quality can be evaluated by a simply visual appraisal, or it can be determined more accurately by scientific tests. Color and Marbling Standards cards are also available.
