Section 79. Examination at request of owner; segregation; grading of herds

The owner of a herd of cattle kept for dairy or breeding purposes within
  the state may apply to the commissioner for examination of his  herd  by
  the  tuberculin,  or  other  approved  tests,  subject  to the following
  regulations:
    1. The application therefor shall be upon a blank form provided by the
  commissioner and shall include an agreement on the part of the owner  of
  the  herd  to  improve  faulty  sanitary  conditions,  to  disinfect his
  premises if diseased cattle be found, and to follow  directions  of  the
  commissioner  designed  to  prevent  the  reinfection of the herd and to
  suppress the disease and prevent the spread thereof.
    2.  The  commissioner  shall  cause  such  cattle   to   be   examined
  accordingly,  subject  to  the  provisions  of  this article, and if any
  animal responds to such test, he may cause it to be slaughtered or  held
  in strict quarantine.
    3.  If  after  examination  an  animal  be  found to be suffering from
  tuberculosis such animal shall be slaughtered under  the  provisions  of
  this  article,  or  the  commissioner may enter into a written agreement
  with  the  owner  for  keeping  such  animal  in  segregation   or   the
  commissioner  may,  if the condition of such animal warrants it, consign
  such animal to any one of the experiment  stations  or  farms  owned  or
  controlled  by the state, or by any county of the state, or to the farms
  of such public institutions in  the  state  as  the  commissioner  shall
  approve,  or to hospitals, sanitariums or other institutions existing in
  whole or in part for the purpose of suppressing tuberculosis,  there  to
  be  kept  and  used  for  breeding, dairy or experimental purposes under
  regulations to be prescribed by the commissioner.
    4. Subject to the rules of the commissioner, an  animal  found  to  be
  diseased  after  such  examination  may continue to be used for breeding
  purposes, but the milk from such  animal  shall  not  be  used  for  any
  purpose until pasteurized at such temperature and for such period as the
  commissioner may prescribe.
    5.  The  young  of  any  such  diseased  animal  shall  immediately be
  separated from its mother and shall not be permitted to  receive  or  be
  fed  the  milk  from  such  affected  animal  until  such  milk has been
  pasteurized as provided in subdivision four of this section.
    6. The commissioner may make rules for classifying herds tested  under
  this  section  and  for the purpose of giving recognition to herds which
  are in a healthy condition,  he  is  hereby  authorized  to  issue  such
  certification  as he may deem proper in relation to such herds.  If such
  rules  and  such  certification  provide  for  periodical   retests   of
  accredited  herds,  or  other herds not yet accredited, the cost of such
  retests, after January first, nineteen  hundred  and  thirty,  shall  be
  borne  by  the  state  and  there  shall be appropriated annually to the
  department a sum sufficient to defray  the  expense  of  the  veterinary
  service for such required retests.
