Iowa Code § 165.26: Permitting test.

Every owner of dairy or breeding cattle in the state shall permit the owner’s cattle to be tested for tuberculosis as provided in this chapter, and shall confine the cattle in a proper place so that the examination and test can be applied. If the owner refuses to so confine the cattle the department may employ sufficient help to properly confine them and the expense of such help shall be paid by the owner. Such owner shall comply with all the requirements for the establishment and maintenance of a tuberculosis-free accredited herd.
