1. The state veterinarian shall require all licensees defined in this chapter to obtain inspection of all livestock offered for sale at any livestock sale or market in the manner that he designates.

2. The state veterinarian, or his deputy, may in his discretion order any livestock vaccinated or quarantined or both if he thinks such action advisable. The authority to require vaccination given herein shall not be construed to give the state veterinarian power to issue a general order for the vaccination of all livestock sold in this state or sold at all livestock sales in this state.

3. Livestock inspections, and all official testing of livestock for disease, including any method of identifying animals in connection with a disease, shall be made by a licensed veterinarian or other person approved by the state veterinarian and whose performance of official tests or inspections shall be in accordance with rules and regulations that may be made by the state veterinarian not contrary to the provisions of this chapter. The veterinary inspector is subject to dismissal by the state veterinarian for neglect of duty in the enforcement of the provisions of this chapter or for misconduct while on official duty. Any market operator who desires to dismiss from his position a veterinarian approved under this section, shall notify the state veterinarian, who shall review the circumstances surrounding the proposed dismissal. The state veterinarian shall provide both the market operator and the market veterinarian an opportunity to appear and be heard. In the event that such circumstances cannot be satisfactorily resolved within thirty days, the state veterinarian shall withdraw approval of the market veterinarian for that market or sale, unless it shall appear that the predominant reason for dismissal is a refusal by the market veterinarian to breach a state or federal requirement relating to the performance of official tests and inspections.
