The commissioner may suspend a producer’s permit if it is found after investigation that circumstances exist which threaten the health or safety of the public. If a producer’s permit is suspended, the commissioner shall provide the permittee with written notice of the basis for the decision and shall, upon request, schedule a hearing before the milk sanitation board. If a hearing is requested, it shall be held within 10 business days of the date requested. No milk producer shall operate during the pendency of any administrative proceeding following suspension of the producer’s permit. If a producer demonstrates that the circumstances resulting in suspension have been corrected, and no longer constitute a threat to the health or safety of the public, the commissioner may reinstate the producer’s permit without requiring a hearing before the milk sanitation board.
