(a) The Commissioner of Public Health shall carry out the commissioner’s responsibilities with respect to enforcement of the provisions of sections 20-206b, 20-206d and 20-206g within available appropriations.

(b) If the commissioner has cause to believe, based upon credible information or complaint, that any person has violated the provisions of § 20-206b, 20-206d or 20-206g, the commissioner may, not later than thirty days after receiving such information or complaint, begin a formal investigation of the alleged violation. In the course of such formal investigation, the commissioner may inquire as to whether a person under investigation obtained a license from the department legally by comparing the photograph on such person’s identification with a photograph of such person obtained from the organization that administered the examination prescribed by the department pursuant to § 20-206b. Photographs that do not match shall constitute prima facie evidence that such person is engaging in the practice of massage therapy without a license in violation of § 20-206b. For purposes of this subsection, “identification” means a motor vehicle operator’s license issued pursuant to § 14-36 or any other valid form of identification issued by the federal government or a state or municipal government, provided such identification includes a photograph.
