Beef from retail and foodservice establishments in 11 US cities was evaluated using Warner–Bratzler shear (WBS) and consumer evaluation panels. Postmortem aging times ranged from 3 to 83 d for retail and 7 to 136 d for foodservice with mean aging times of 22.6 d and 30.1 d, respectively. For retail, the three cuts from the round – top round, bottom round, and eye of round – had the highest (P c; 0.05) WBS values compared to cuts from the chuck, rib, and loin. Top loin steaks had the lowest (P c; 0.05) WBS value compared to ribeye and top sirloin foodservice steaks. Retail bone-in top loin, top loin, ribeye, T-bone, and porterhouse received the highest (P c; 0.05) ratings by consumers for overall like and like tenderness. Quality grade had little or no effect on foodservice sensory evaluations. Improvements in round tenderness are needed to increase consumer acceptability.
