(a) Whenever the commissioner finds, after investigation, that the distribution in intrastate commerce of any class of food may, by reason of contamination with microorganisms during the manufacture, processing or packing thereof in any locality, be injurious to health, and that such injurious nature cannot be adequately determined after such articles have entered intrastate commerce, he then, and in such case only, shall promulgate regulations providing for the issuance, to manufacturers, processors or packers of such class of food in such locality, of permits to which shall be attached such conditions governing the manufacture, processing or packing of such class of food, for such temporary period of time, as may be necessary to protect the public health; and, after the effective date of such regulations, and during such temporary period, no person shall introduce or deliver for introduction into intrastate commerce any such food manufactured, processed or packed by any such manufacturer, processor or packer unless such manufacturer, processor or packer holds a permit issued by the commissioner as provided by such regulations. Such regulations shall conform, so far as practicable, with those promulgated under Section 344 (a) of the federal act.

(b) The commissioner is authorized to suspend immediately, upon notice, any permit issued under authority of this section, if it is found that any of the conditions of the permit have been violated. The holder of a permit so suspended shall be privileged at any time to apply for the reinstatement of such permit, and the commissioner shall, immediately, after prompt hearing and an inspection of the factory or establishment, reinstate such permit, if it is found that adequate measures have been taken to comply with and maintain the conditions of the permit, as originally issued or as amended.

(c) Any officer or employee designated by the commissioner shall have access to any factory or establishment, the operator of which holds a permit from the commissioner, for the purpose of ascertaining whether or not the conditions of the permit are being complied with, and denial of access for such inspection shall be ground for suspension of the permit until such access is freely given by the operator.
