(a) The commission may establish a quarantine against all or the portion of a state, territory, or country in which the commission determines scabies exists. A quarantine established under this section is governed by Chapter 161, except that only a scabies inspector recognized by the commission for that purpose in the quarantine notice may issue certificates or permits for the movement of cattle subject to the quarantine. A person who violates the quarantine is subject to the penalties provided by Chapter 161.
(b) If an inspector determines that a scabies infection or exposure exists in a county or area of this state, on any premises, including a road, pasture, lot, yard, stockyard, or enclosure, or among any cattle or sheep, the commission may quarantine the area, premises, or animals.
