CHILLING THE CARCASS
The surfaces of freshly slaughtered hog 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 can be wrapped in a sheet, hung, and chilled in a well-ventilated shed. Wrapping with clean cloth will partially protect the carcass from contamination.
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 a local locker plant or market for chilling. The need for prompt and thorough chilling of warm carcasses cannot be over-emphasized for the inhibition of bacterial growth. The carcass can be cut into retail cuts after it has been chilled for 24 to 48 hours.
