  1. Carcass Disposal Options Josh Payne, Ph.D. Area Animal Waste Mgmt. Specialist OSU Cooperative Extension Service

  2. Carcass Disposal • Confronts most farmers at some point • Producer must take responsibility • Otherwise state authorities will intervene

  3. Improper Disposal • Risks to ground and surface water • Risks to human and animal health • Neighbor/Nuisance complaints

  4. Catastrophic Mortality Loss • Any mortality exceeding the capacity of the current disposal system to accommodate losses within 24 hrs.

  5. Catastrophic Losses • Disease outbreak • Mother Nature (lightning, frozen pond) • Power failure in poultry house

  6. Worst Case Scenario • Estimated 10% death loss on 2 million head of stocker in state equals 200,000 carcasses • Estimated 10% death loss on 300 million broilers in state equals 30 million carcasses • Avian Influenza: 270 – 300 million carcasses • Foot and Mouth: 1.8 – 2 million carcasses

  7. Regulations • OK Dept. Ag. Food and Forestry - regulates carcass disposal • Must be contacted during catastrophic mortality loss • Disposed of in approved manner • Contact D.J. Parrish – Director Ag. Environ. Mgmt. Services (405) 522 6357

  8. Criminal Statutes

  9. Carcass Disposal Options(State Approved) • Rendering • Landfills • Burial • Incineration • Composting

  10. Rendering • Cooking the product and converting into animal feedstuff • Meat and bone meal • Expense and logistics of collecting small volumes frequently is major hurdle

  11. Rendering • No longer available in OK unless: - transport to rendering facility - pay fee • Valley Proteins accepts carcasses (located West of El Reno)

  12. Landfills • Currently 13 counties located E. I-35 w/ landfills accepting livestock carcasses Note: • some landfills require prior notification before delivery and • some require documentation concerning livestock’s cause of death • Consider tipping fees: $20-$25/ton

  13. Burial • Perhaps most realistic option • May be costly • OK. Dept. Ag. Food & Forestry (ODAFF) guidelines

  14. ODAFF Burial Guidelines • Burial of dead livestock requires the construction of a pit. • Do not locate the burial pit closer than 1 ft. vertically above the flood plain, or within 2 ft. of the water table or bedrock. • Do not locate the burial pit within 300 ft. of wells, waters of the state, neighboring residencies, public areas or property lines. • After placing the dead carcasses in the trench, cover with a minimum of 2.5 ft. of topsoil. Inspect burial sites routinely to ensure that wild animals are not digging and dragging them away.

  15. ODAFF Burial Guidelines • CAFOs and RPFOs must receive permission from ODAFF (unless written into AWMP) • Recommend using soil w/proper drainage - sandy clay loam

  16. Incineration • Open-air incineration not allowed unless animal died of contagious or infectious disease. • Self contained, closed incinerators and air curtain incinerators allowed. • May require permit. • Contact ODEQ Air Quality Division.

  17. Composting • Heavy equipment requirement • Environmentally friendly • Effective • Valuable by-product • Can be labor intensive

  18. Composting • Definition: Controlled biological decomposition process that converts organic matter to stable, humus-like product • Bulk is reduced 35 – 40%

  19. Composting • CAFOs and RPFOs must receive permission from ODAFF (unless written into AWMP)

  20. Composting Components • Nitrogen source (animals/birds) • Carbon source (straw, shavings) • Aerobic microorganisms

  21. 4 Important Aspects • Carbon • Air flow • Moisture content • Temperature

  22. Your Job? • Manage to provide right food and environment for microorganisms so that they can get their composting work done quickly and effectively!

  23. Composting Livestock • Place 12 inches bulking agent on bin concrete floor • Place carcasses on single layer • Cover with 12 inches of bulking agent • Add water as needed • Place additional carcasses on pile using 12 inches bulking agent between layers • When bin is full, add 12 inches to top • Peaks in temp from 140°F to 160°F • Temp drops after depleting available O2 • Move to secondary bin • Aerate by keeping bucket high • Add 12 inches to top • Second heating • Remove and place in storage (3rd heating) • Spread on crop fields

  24. Composting Poultry • 1/10 part straw, 1 part weight dead poultry, 1.5 to 2 parts weight poultry litter • Mixture = 25:1 C:N ratio, 45% moisture

  25. Composting Poultry • 12 inches litter on bin concrete floor • Add layers of straw, dead birds and litter • Cover each day’s mortality w/ litter • When bin is full add 6 inches of litter to top • Peaks in temp from 140°F to 160°F • Temp drops after depleting available O2 • Move to secondary bin • Aerate by keeping bucket high • Add 6 inches of litter to top • Second heating • Remove and place in storage (3rd heating) • Spread on crop fields

  26. Composting Poultry Mass Mortality Most pathogens and viruses killed at 135 – 155 °F
