The director of health or the director’s officer or agent may enter any place where olive oil is packed, labeled, distributed, or offered for sale for the purpose of examining into any suspected violation of § 21-21-2 and § 21-21-3; and whenever the director has reason to believe that any olive oil is being packed, labeled, distributed, or offered for sale in violation of § 21-21-2 and § 21-21-3, he or she shall take specimens of the oil and cause the specimens to be analyzed or satisfactorily tested, the result of which he or she shall record and preserve as evidence, and a certificate of the result, sworn to by the analyzer, shall be admissible in evidence in all prosecutions under this chapter. Every person refusing the director or other officer or agent responsible entry for the purpose of examination, or refusing to allow him or her to take specimens, shall, upon conviction, be fined a sum not exceeding fifty dollars ($50.00).
