Tests and check tests by the commissioner

A. (1) In the event the purchaser or cooperative elects to pay producers for butterfat on the basis of a composite sample, the commissioner may secure and test fresh milk samples on daily shipments of producer milk as a means of checking the accuracy of work performed by licensed personnel and require payment on the basis of the commissioner's test when the comparison reveals a variation in excess of one-tenth of one percent. The commissioner may also examine and check test the composite samples to ascertain their accuracy. (2) If after a hearing the commissioner determines that a purchaser or cooperative has inadequate testing facilities or equipment or personnel, and the purchaser or cooperative will not contract for the performance of the testing services by the commissioner in accordance with R.S. 3:4002(7), the commissioner may conduct the testing program for the purchaser or cooperative on behalf of the producers involved in the same manner as herein provided for the purchaser or cooperative; require payment to producers in accordance therewith; and make the same reports to producers as provided for herein. (3) In the event the purchaser or cooperative elects to pay producers for butterfat on the basis of fresh milk samples, the commissioner may secure and test such fresh milk samples as he deems necessary to verify the correctness of the fresh milk sampling program of the purchaser or cooperative, and require payment on the basis of the commissioner's tests when the comparison reveals a variation in excess of one-tenth of one percent. (4) The commissioner shall not perform, nor shall he authorize any purchaser or cooperative to perform any fresh sample testing program that shall incorporate less than three proven and acceptable fresh milk tests within a semimonthly testing period nor less than six such tests within a monthly testing period. The tests shall be stratified, as nearly as possible, so as to assure at least one fresh milk test within each five days of the shipping period. The fresh milk testing program shall represent not less than one-third of the total producer shipments within a partial period of shipment. (5) The requirements contained herein and as otherwise defined by rule and regulation shall be binding upon the commissioner and any cooperative or purchaser authorized by the commissioner to perform this service. B. Any person licensed to measure, sample, transport, collect or test milk samples as a basis of payment to producers shall upon request by the commissioner, secure and submit data, records, and/or fresh milk samples necessary for investigation by the commissioner. C. In order to facilitate the taking of accurate samples by the commissioner, any purchaser, cooperative, person, firm, or corporation purchasing, handling, or transporting milk in bulk milk tank trucks shall provide adequate agitation facilities at points of delivery. D. The commissioner may secure processed or finished product samples as a means of checking the utilization of fat and skim by purchasers and cooperatives in such manner as shall be defined by rule and regulation.
