(a) The commission shall immediately quarantine cattle and the premises on which the cattle are located if the cattle show a positive reaction when tested for tuberculosis by a veterinarian recognized by the commission for that purpose.
(b) Before the establishment of a quarantine a person may not move the cattle that show a positive reaction from the enclosure in which they were located at the time of testing, and may not sell, trade, barter, grant, or loan those animals. After a quarantine is established, a person may not move any cattle from the quarantined premises without first obtaining a written permit from the commission.
