Pork Primal Cuts

Pork primal cuts are the large sections into which a pig carcass is divided during primary butchery. The exact number and names of primals vary by country and cutting system. In North American fabrication, the main pork primals are shoulder, loin, belly (side) and leg (ham). The carcass may also be divided into smaller subprimals and retail cuts for foodservice.

North American pork primals

• Shoulder: divided into the Boston butt (upper shoulder) and picnic shoulder (lower foreleg section). Used for pulled pork, sausages, braises and roasts.
• Loin: the back section containing the loin muscles and baby back ribs. Fabricated into loin roasts, chops, tenderloin and rib sections.
• Belly or side: the underside of the pig, with alternating layers of meat and fat. Used for fresh pork belly, bacon and pancetta.
• Leg or ham: the hind leg, sold fresh, cured, smoked or cooked. It may be divided into inside, outside, knuckle and shank portions, depending on the cutting system.

Regional terminology

British butchery commonly identifies shoulder, loin, belly, leg and hand. French fabrication uses terms such as échine (neck/upper shoulder), carré (rib section), filet mignon (tenderloin), longe (loin), poitrine (belly), jambon (ham) and jarret (shank). These terms do not always map exactly onto North American primals.

Why primal identification matters

Each primal contains muscles with different tenderness, fat cover, connective tissue and usable yield. The fabrication determines which cuts are suitable for quick cooking, roasting, braising, curing or grinding. Accurate identification is essential for purchasing, recipe development and menu costing.

Example: use pork loin for chops and roasts, shoulder for pulled pork, belly for bacon or braised pork belly, and leg for fresh roasts or cured ham.

Chef’s tip: Specify the primal, subprimal, bone status, skin status, trim and weight range on purchase orders. Use supplier cut diagrams where regional names differ.
