The Department of Agriculture shall establish rules for determining when a herd of cattle, bison, goats, or cervids shall be considered as tuberculosis-free. When any herd meets such requirements the owner shall be entitled to a certificate from the Department of Agriculture showing that the herd is a tuberculosis-free accredited herd. Such certificate shall be revoked whenever the herd no longer meets the necessary requirements for an accredited herd, but the herd may be reinstated as an accredited herd upon subsequent compliance with such requirements. “Herd” as herein used shall include one or any number of cattle, bison, goats, or cervids.
