CHILLING THE CARCASS
The surfaces of freshly slaughtered beef carcasses are contaminated with bacteria that can spoil the meat unless their growth is promptly checked. Bacterial growth can be slowed by prompt chilling and keeping the carcass at low temperatures. If the weather is suitable (28° to 35° F), the carcass or quarters can be wrapped in a sheet and hung to chill in a well-ventilated shed. Wrapping with a clean cloth will partially protect the carcass from contamination and help smooth out the fat on the outer surface.
Do not allow the carcass to freeze because freezing within 1 day after death may toughen the meat. If the carcass cannot be chilled to below 40°F on the farm, it should be transported to the local locker plant or market for chilling. Chilled beef should be aged at least 2 to 3 days to ensure that rigor is complete. There is no benefit to aging beyond 7 to 9 days. In fact, subsequent freezer storage life may be reduced by long aging periods.
CUTTING
Use the following guidelines to prepare cutting and packaging instructions for the plant if the carcass is not cut and wrapped on the farm.
Steaks.—Those from the loin and rib, which are to be broiled, should be an inch or more in thickness. Those from the round and chuck, or which are to be cooked slowly with moist heat, should be ½ to ¾ inch thick. If two or more steaks are packaged together, they should be separated by two sheets of plastic or moisture-resistant paper. Although the size and shape of a steak will largely determine how many servings it will yield, allow ¾ of a pound per person (bone-in uncooked) where practicable.
Roasts.—Allow ¾ pound (uncooked) per serving for bone-in roasts such as blade chuck roasts or rump roasts and ½ pound (uncooked) per serving for boneless roasts such as sirloin tip or heel of round.
Ground beef and stew meat.—Allow ½ pound (uncooked) per serving.
