2 CERTIFICATION

Carcasses to be examined for compliance with this specification will be clearly identified and

of preliminary identification marks (or other methods of control) from non-qualifying carcasses, and 

control of certified carcasses shall be in accordance with established Quality Assessment Division 

(QAD) procedures.

1 Determined in accordance with the “Official United States Standards for Grades of Carcass Beef.” 2 Evaluated using the USDA-AMS-LS-SB-02 Marbling Texture card (included in the Official USDA Marbling Photographs.) 3 Muscle thickness is evaluated by averaging the thickness of the various parts, considering not only the proportion of each part of the 

carcass but also the general value of each part. Superior muscle thickness implies a high proportion of meat to bone and a high 

proportion of the weight of the carcass in the more valuable parts.

4 Measured from a line formed by the extension of the top line (including the fat) and measuring the lean muscle (excluding the fat) 

perpendicular to that line in the center of the hump.
