California Code, Food and Agricultural Code (Formerly Agricultural Code) - FAC § 57301

The commissioner shall require any person, except a county, state, or federal inspection agency, who, for payment by a private party, reports upon the condition of lots of fresh fruits or vegetables offered for sale other than for processing to register with the commissioner. The commissioner shall maintain a registry of these persons which shows the name and business address, market or markets at which inspections are made, the products inspected, and additional matters that the commissioner requires. The commissioner shall forward this information to the director who shall maintain a central registry on a statewide basis. A produce inspector who is registered in one county where he or she does business may do business in any other county without registering in the other county if the commissioner in the other county is provided proof of registration.
