(1) Except as set out in subsections (2) and (3) of this section and section 54-776, it is the duty of the owner or custodian of any dead animal to cause such animal, within thirty-six hours after receiving knowledge of the death of such animal, to be:
(a) Buried at least four feet below the surface of the ground or completely incinerated or composted on the premises where such animal dies or on an adjacent property under the ownership and control of the owner or custodian. Any vehicle used by the owner or custodian to transport such dead animal shall be constructed in such a manner that the contents are covered and will not fall, leak, or spill therefrom. Violation of this subdivision is a traffic infraction as defined in section 60-672; or
(b) Transported by a licensed rendering establishment to either a rendering establishment licensed under the Nebraska Meat and Poultry Inspection Law or to a facility with a permit to operate as a landfill under the Integrated Solid Waste Management Act. The operator of a landfill is not required by this subdivision to accept dead animals.
(2) The Department of Agriculture shall regulate the composting of livestock carcasses and shall adopt and promulgate rules and regulations governing the same. Any person incorporating livestock carcasses into a composting facility shall follow the operating procedures established by the Department of Agriculture in consultation with the University of Nebraska Institute of Agriculture and Natural Resources.
(3) An animal carcass or carcass part may be transported by the owner or the owner's agent to a veterinary clinic or veterinary diagnostic laboratory for purposes of performing diagnostic procedures.
