Whenever an owner requests of the director of public health that his cattle be tested
for tuberculosis, the expense of such test shall be borne by the owner, unless said
request is made under the provisions of the Food and Agricultural Code of the state
of California, and said owner agrees, in writing, to conform in all respects to said
state law and the rules and regulations of the director of public health applying
to tuberculin tests and disposal of reacting animals; provided, that whenever five
or less cattle are sold for dairy and breeding purposes and test for tuberculosis
is required under the provisions of this chapter, the director of public health shall,
at the request of the owner thereof, conduct one such test without charge within a
period of six months.
