  3. Processing Livestock • Meat companies purchase livestock for processing • Tyson, Holly Farms • Oscar Myers • Smithfields • Browns

  4. Processing Livestock • Two methods of purchasing by meat companies • Contract basis • Auction sale

  5. Processing Livestock • The USDA inspects livestock before, during and after processing. • Veterinarian inspectors • Approved meat receives an USDA stamp and grade

  8. Processing Livestock

  9. Processing Livestock • Beef cattle and swine are bled by cutting or sticking • Main artery • Jugular vein

  10. Processing Livestock • Livestock are processed to use all available parts: • Meat • Hide for leather in cattle • Bone meal • Blood meal • Hoofs and horns • Fatty acids

  11. Processing Poultry Steps in processing: • Stunning is done to make the bird unconscious • Does not kill the bird • Some religious groups require the animal not be stunned prior to slaughter • Bleeding • Cutting jugular vein without cutting the esophagus

  12. Processing Poultry • Scalding loosens feathers • Picking removes feathers • Mechanical • Removing feet, neck, skin and preen gland

  13. Processing Poultry • Evisceration performed • Removing entrails • Carcass is chilled • Ice water • Less than 40 degrees F

  14. Objective • Describe the USDA inspection process for livestock and poultry products

  15. USDA Inspection • Began in 1891 • Ante mortem inspection • Before death • Check for disease • Abnormalities
