Section 57-A. Licensing of persons making bacterial counts of milk and/or cream or making tests of milk and/or cream to detect certain abnormalities

No  person  shall  test  milk and/or cream in order to  determine the bacterial or  leucocyte  count  or  make  other  tests  to
  determine the presence or absence of abnormal milk, where the results of
  such  test  affects  the  rate  of payment to the producer for such milk
  and/or cream, the classification of milk and/or cream as  received  from
  the  producer,  or the acceptance or rejection of such milk and/or cream
  by the operator of  a  milk-receiving  or  manufacturing  plant,  unless
  licensed by the commissioner. Application for such license shall be made
  upon  a form prescribed by the commissioner. The applicant shall furnish
  satisfactory evidence of good moral character, and shall demonstrate his
  ability to make such tests by an examination under the direction of  the
  commissioner.  The  applicant shall pay a license fee of five dollars to
  the commissioner for remittance to the state treasury. A  license  shall
  be  for  a  period not exceeding five years. A license may be renewed in
  the  discretion  of  the  commissioner,  without  an  examination,   for
  successive  periods  of  not exceeding five years each upon payment of a
  license fee of two dollars to the commissioner  for  remittance  to  the
  state treasury.
    Each  license shall be kept at the place where the licensee is engaged
  in testing milk and/or cream and shall be open to inspection.
    A license may be revoked by the commissioner, after a hearing upon due
  notice to the licensee, for dishonesty, incompetency,  inaccuracy  or  a
  violation of the provisions of this article.
