II. Background

A. What Action is the Agency Taking?

Section 4 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) directs EPA to reevaluate existing pesticides to ensure that they meet current scientific and regulatory standards. In 2006, EPA signed a RED for iodine and iodophor complexes under section 4(g)(2)(A) of FIFRA. An additional amendment was signed on March 17, 2009.

Taking into consideration all available information on iodine, including its relatively low acute toxicity, the reversibility of subclinical hypothyroidism, the low toxicity of the iodophor complexes, the Food and Drug Administration's designation of iodide as a “Generally Recognized As Safe (GRAS)” chemical, the presence of iodine in food products, and the sporadic and short-term nature of the antimicrobial uses, the Agency concludes that exposure to iodine and iodophor complexes from the EPA-registered uses present no risk of concern. No mitigation measures are necessary at this time. The March 17, 2009 amendment to the Iodine and Iodophor Complexes RED is inclusive of a Labeling Changes Summary Table and a revised Appendix A. The label table incorporated into the Iodine and Iodophor Complexes March 17, 2009 RED amendment includes modifications which specify label language for emergency human drinking water use. Appendix A is inclusive of the current EPA-registered products containing iodine or an iodophor complex as an active ingredient.

B. What is the Agency's Authority for Taking this Action?

Section 4(g)(2) of FIFRA, as amended, directs that, after submission of all data concerning a pesticide active ingredient, “the Administrator shall determine whether pesticides containing such active ingredient are eligible for reregistration,” before calling in product specific data on individual end-use products and either reregistering products or taking other “appropriate regulatory action.”
