§ 135-a. Inspection, sampling and analysis. 1. For the purpose of enforcing this article, and in order to determine whether its provisions have been complied with, including whether or not any operations may be subject to such provisions, officers or employees of the department, upon presenting appropriate credentials and, if feasible, a written notice to the owner, operator, or other person in charge, are authorized (a) to enter, at all reasonable times, any factory, warehouse, or establishment within the state in which commercial feed or feed ingredients may be manufactured, processed, packed, or held for distribution, or to enter any vehicle which may be used to transport or hold such feed or ingredients; and (b) to inspect, at all reasonable times, such factory, warehouse, establishment or vehicle and all pertinent equipment, finished and unfinished materials, containers, and labeling therein, and to obtain samples thereat.

2. If the officer or employee making such inspection of a factory, warehouse, establishment or vehicle has obtained a sample in the course of the inspection, if feasible, upon completion of the inspection and prior to leaving the premises, he shall give to the owner, operator or other person in charge a receipt describing the sample obtained.

3. Sampling and analysis shall be conducted in accordance with methods published by the Association of Official Analytical Chemists, or in accordance with other generally recognized methods as approved by the commissioner.

4. The results of all analyses of official samples shall be forwarded by the commissioner to the person in whose name the brand of such feed is registered under section one hundred twenty-nine of this article, or if there be no such registrant for the same, then to the person named on the label or invoice, delivery slip or other document for such feed, or if the commissioner deems it appropriate, to the person from whom the sample was obtained. When the analysis of an official sample indicates a commercial feed has been adulterated or misbranded, upon request by the person receiving such results within fifteen days following the receipt thereof, the commissioner or his authorized agent shall furnish such person a portion of the sample concerned.
