Examining the Carcass
All the internal organs and the dressed carcass should be examined carefully for any abnormalities or conditions that might affect the fitness of the meat for food. Usually, a meat inspector or graduate veterinarian is the only person qualified to do this, but under farm conditions it becomes necessary for you to look for the obvious signs of disease or damage. If any part of the viscera or carcass is questionable, you should obtain expert advice.
Bruises, minor injuries, parasites in the organs, and enclosed abscesses, and single tumors are frequently local conditions that can be easily removed. However, the presence of congestion or inflammation of the lungs, intestines, kidneys, inner surface of chest or abdominal cavity and numerous yellowish or pearl-like growths scattered throughout the organs should be viewed seriously. Carcasses and viscera having such abnormalities should be examined by a graduate veterinarian and his opinion obtained as to the wholesomeness of the meat. You should check with a cooperating veterinarian before slaughtering the animal to be certain he will be available if you should seek his advice.
CHILLING THE CARCASS
Following evisceration, the lamb carcass should be carefully trimmed and any pieces of adhering skin, wool, bruises, hair, or manure removed. Lamb carcasses are not split longitudinally because they are not thick enough in any dimension to create cooling problems.
The surfaces of freshly slaughtered lamb 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 one 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. The need for prompt and thorough chilling of warm carcasses cannot be over-emphasized. The carcass can be cut into retail cuts after the carcass has been chilled for 24 to 48 hours.
CUTTING
Use the following guidelines to determine cutting and packaging instructions for the processor if the carcass is not cut and wrapped on the farm.
