Health & Saf. Code, § 110430

Whenever the department finds that a class of food distributed in this state may, by reason of contamination with micro-organisms during manufacture, packing, or storage, be injurious to the health of any man or other animal that consumes it and that the injurious nature cannot be adequately determined after this food has entered commerce, the department shall adopt regulations providing for the issuance of permits to manufacturers, processors, or packers of the class of food. These permits shall establish conditions governing the manufacture, packing, or storage of the class of food for the period of time as may be necessary to protect the public health. The regulations shall prescribe a date after which no person shall introduce or deliver for introduction into commerce any food manufactured, packed, or stored by any manufacturer, processor, or packer, unless the person holds a permit issued by the department as provided by the regulations.
