Such procedures, including the certification of sample collectors and examinations shall be evaluated by the state health officer in accordance with the Evaluation of Milk Laboratories. Aseptically processed milk and milk products packaged in hermetically sealed containers shall be tested in accordance with the Bacteriological Analytical Manual. Examinations and tests to detect adulterants, including pesticides, shall be conducted as the state health officer requires. Assays of dairy products to which vitamin A, vitamin D or vitamins A and D have been added, shall be made at least annually in a laboratory which has been accredited by the U. S.
