Sec. 163.066.  REGULATION OF MOVEMENT OF CATTLE;  EXCEPTION.  (a)  As a control measure, the commission by rule may regulate the movement of cattle.  The commission may restrict the intrastate movement of cattle even though the movement of the cattle is unrestricted in interstate or international commerce.  The commission may require testing, vaccination, or another procedure that is epidemiologically sound before or following the movement of cattle.
(b)  The commission may not adopt a rule that prohibits a person from moving cattle owned by that person within unquarantined contiguous lands owned or controlled by that person.
(c)  Any restriction on the movement of cattle imposed under provisions of this chapter may be modified or set aside by the commission upon application by the cattle owner, provided that the owner can show impending unusual hardship resulting from such restriction.  Contributory factors may include but are not limited to prolonged drought, inadequacy of pasturage or usual feed supply resulting from disaster or other unforeseeable circumstance, or economic hardship of the cattle owner;  provided that individual animals under restriction shall be handled in a manner to be prescribed by the commission.
