2. There are following method of disposal of spoiled
Meat
1.Burning
2.Landfills
3.Compositing
4.Burial
5.Extrusion
6.Alkaline hydralosis
3. On-farm disposal of dead dairy cows in such a manner as not to
become a nuisance on-site or to neighbors, to prevent spread of
disease to other cattle and to protect the public health and safety.
Objectives
Who is Responsible
Owner is responsible for burial in a timely and
sanitary manner.
Timing After Death
Buried within a reasonable time period, i.e. 24-
48 hours after death. Buried prior to creation
of adverse public health or nuisance
4. Each animal should be buried in a separate pit, unless mass
burial is found necessary in an emergency situation to protect
public health or the health of other livestock or wildlife. State
or Federal veterinarian should probably be responsible for
declaring an emergency.
HowBuried
Deep enough to cover the top of the carcass with 4-6 feet of
compacted soil and earth, and in an area not likely to be disturbed in
the near future.
How Deep
Where
Far enough from standing or flowing or ground water to prevent
contamination of these waters and in an area not likely to be
disturbed in the near future.
5. Burial
When a site acceptable to the local environmental protection agency is available, burial is
usually the preferred method of disposal. In selecting a burial site, it is necessary to consider
the adequacy of soil depth and to avoid underground electrical cables, water pipes, gas pipes,
septic tanks, and water wells.
Burial Pit
Width . . . . . . . .2.3 meters
Depth . . . . . . . . 3meters (7*9feets)
Length . . . . . . . 5meters
9. Burning:
Burning in an incinerator that is operated in compliance with local laws and ordinances
is an excellent means to dispose off spoiled meat.
Burning carcasses in an open site should be done only when legally permitted.
The burn site should be away from public places.
Carcasses must be placed on a quantity of combustible supporting materials sufficient
to reduce them completely to ashes. The material must also be arranged in a manner
to permit an adequate flow of air to the fire. Gasoline or other highly volatile
combustible liquids should not be used.
Fire Bed
To prepare the fire bed, an area of ground should be staked out to accommodate the
number of carcasses to be burned: 8 × 3 ft for each mature cow or horse, 5 mature pigs
or sheep, 100 mature chickens, or 40 mature turkeys. The fire bed burns best if at a
right angle to the prevailing wind.
Under favorable conditions, burning should be complete in 48 hr. When the fire has
died out, the ashes should be buried and the area cleaned, graded or plowed, and
prepared for seeding.

11. Composting :
This method involves the above ground decomposition of animal carcass over a period of time.
The composting process must be managed at all times to be practically odorless, prevent fly
larvae development, prevent animal depredation and stop leaching of waste material thereby
becoming a source of water/soil contamination.
2. The carcass must be reduced to brittle/easily broken bone.
3. A minimal peak temperature of 130 F and a minimal 110 F maintenance temperature must be
achieved during the composting process to where the finished product is pathogen free.
Composting – Exposed to Weather
1. Approved for all large animals (swine, ruminants, horses etc.).
2. 2. Compost material (carbon source) may be sawdust, hay, etc. but may not contain manure.
3. The carcass must be placed on at least a 24 inch thick pad of compost material that is large
enough so that when the carcass is placed there will be at least 24 inches from the carcass to
the edge of the pad.
4. A layer of compost material that completely covers the carcass and is at least 24 inches thick
must be maintained throughout the composting process.

13. c. Composting – Protected from Weather
1. Approved for all large animals (swine, ruminants, horses
2. Compost material (carbon source) may be saw dust, hay etc. and may contain
manure.
3. Composting must be done in a bin(s) that has a concrete floor to provide an all-
weather base, roof to exclude excess moisture and rot resistant bin construction to
support the compost material and withstand stresses applied by tractor loader.
4. Carcass are to be placed in the compost bin on at least a 12 inch thick base pad of
compost material and carcass can not be placed within 8 inches of the sides, front or
rear of the compost bin.
5. A layer of compost material that completely covers the carcass must be
maintained throughout the composting process.
14. Alkaline Hydrolysis
This process uses sodium hydroxide or potassium hydroxide under heat and
pressure to digest carcass tissue.
The resulting effluent typically has a pH level of 11.4 to 11.7, and in most cases,
can be discharged into municipal sewage systems.
The process does require specialized, expensive equipment therefore this method
has limited application in a disease outbreak situation.
15.
16. Rendering
Rendering is the most economical method of
disposing of carcasses, however movement of
infected carcasses to rendering plant locations,
may pose some risk of disease spread, so
preventive precautions must be taken.
Landfill
The use of landfills for carcass and material disposal may be an option.
The necessary equipment, personnel, procedures and containment
systems are already in place and may be useful. However, the transport
of carcasses to these locations may pose some risk of disease spread.
