(a) The health officer may, upon written notice, without prior warning, notice or hearing, suspend any permit to operate a retail food store or food service establishment if the operation of the retail food store or food service establishment constitutes an imminent or substantial hazard to the public health, such as an extended loss of water supply, an extended power outage or sewage back-up into the establishment, or if such operation is not in compliance with the requirements of this division. When such permit is suspended, retail food store or food service establishment operations shall be suspended immediately.
(b) Whenever a permit to operate a retail food store or food service establishment is suspended, the holder of the permit to operate the retail food store or food service establishment, or the person in charge, shall be notified in writing that the permit to operate the retail food store or food service establishment is, upon service of the notice, immediately suspended and that an opportunity for a hearing will be provided if a written request for a hearing is filed with the health officer by the holder of the permit within ten days. If a written request is filed within ten days, an opportunity for a hearing with the health officer shall be afforded within 20 days of receipt of the request. If no written request for a hearing is filed within ten days, the suspension is sustained. The health officer shall end the suspension if the reasons for the suspension no longer exist.
