(1) Any added poisonous or deleterious substance, food additive, pesticide chemical in or on a raw agricultural commodity, or color additive, with respect to any particular use or intended use, shall be deemed unsafe for the purpose of application of section 25-5-410 (1)(b) with respect to any food, section 25-5-414 (1)(a) to (1)(f) with respect to any drug or device, or section 25-5-416 (1)(a) with respect to any cosmetic, unless there is in effect a regulation pursuant to section 25-5-419 or subsection (2) of this section limiting the quantity of such substance and the use or intended use of such substance is within the limits prescribed by such regulation. While such a regulation relating to such substance is in effect, a food, drug, or cosmetic, by reason of bearing or containing such substance in accordance with the regulations, shall not be considered adulterated within the meaning of section 25-5-410 (1)(b), 25-5-414 (1)(a) to (1)(f), or 25-5-416 (1)(a).
(2) The department, whenever public health or other considerations so require, is authorized to adopt, amend, or repeal regulations upon its own motion or upon the petition of any interested party, whether or not in accordance with regulations promulgated under the federal act.

If the data furnished by the petitioner are not sufficient to allow the department to determine whether such regulation should be promulgated, the department may require additional data to be submitted, and failure to comply with the request shall be sufficient grounds for denial of the request.
