(v) As specified in a herd or flock management plan; or

(vi) In the event of a disease, natural disaster, or other emergency event resulting in catastrophic livestock mortality or euthanization, to a location designated by a county or other local emergency management organization.

(4) It is hereby made the duty of the sheriff of each county to cause the proper disposal of the carcass of any animal or carcass part remaining unburied or otherwise disposed of after notice from the department that any such carcass has not been properly buried or disposed of in violation of this section. The sheriff may enter any premises where any such carcass is located for the purpose of carrying out this section and may cause each carcass to be properly buried or disposed of on such premises. The county board of commissioners or supervisors shall allow such sums for the services as it may deem reasonable, and such sums shall be paid to the persons rendering the services upon vouchers as other claims against the county are paid. The owner of such animal shall be liable to the county for the expense of such burial or disposal, to be recovered in a civil action, unless the owner pays such expenses within thirty days after notice and demand therefor.

(5) If anthrax is suspected in any animal death, the owner or custodian of the animal or herd shall be responsible to have samples submitted to an approved laboratory for confirmation.

(a) Transport such animal or animal carcass, except as directed and approved by the department;

(b) Use the flesh or organs of such animal or animal carcass for food for livestock or human consumption; or

(c) Remove the skin or hide of such animal or animal carcass.

(7) The disposition of any anthrax-infected animal carcass shall be carried out under the direction of the department. It shall be the duty of the owner or custodian of an animal that has died of anthrax to bury or burn the carcass on the premises where the carcass is found, unless directed otherwise by the State Veterinarian. If such carcass is buried, no portion of the carcass shall be interred closer than six feet from the surface of the ground. The department may direct the owner or custodian of an infected herd to treat the herd and to clean and disinfect the premises in accordance with the herd plan.
