All market milk distributed in the county in the final package for human consumption shall be pasteurized except that certified raw milk, as defined in Agricultural Code Section 35921, may be sold provided such milk is produced at dairies, which, at the time of the production of such milk, are in compliance with all of the following conditions:

    A.    All cattle shall be examined annually to determine the presence or absence of carriers of Salmonella Dublin. Such examination shall consist of three successive fecal cultures on each animal taken at not less than two-week intervals. Any animal found to be a carrier of Salmonella Dublin shall be immediately segregated, removed from the herd and sent to slaughter.

    B.    All replacement stock shall be examined and cultured as provided in subsection A of this section and shown to be free of Salmonella Dublin infection by such procedure before entering the certified herd.

    C.    Stool cultures for all enteric pathogens shall be performed annually on all milking personnel and other employees having animal contact or who work in the milk processing plant.

    D.    Daily coliform counts shall be taken on the milk. The dairy shall advise the county health officer where the milk is produced and processed of any coliform count in excess of ten per milliliter.

    No certified raw milk shall be sold within the unincorporated territory of the county unless and until satisfactory evidence of compliance with conditions A, B, C and D is submitted to and approved in writing by the health officer of the county, which approval shall be good for one year from the date thereof. Evidence of compliance shall thereafter be submitted annually. The county health officer shall, immediately upon enactment of the ordinance codified in this chapter, forward a copy thereof to each producer of certified raw milk within the state.
