{Past Event} - Greening Operation Series: Regulatory update: Antimicrobial Labeling Update from the EPA

July 30, 2009 - 3:00 pm - July 30, 2009 - 3:00 pm -- Eastern Standard Time


The Environmental Protection Agency said June 12 that approximately one-third of 325 registered hospital disinfectants and 36 of the 72 tuberculocides tested thus far under the Antimicrobial Testing Program (ATP) failed to meet its standards for effectiveness against bacteria. Products failing the tests “are brought into compliance through regulatory or enforcement measures, or a combination of both,” EPA said.

EPA has already ordered changes to the antimicrobial claims on some product labels and is reviewing others, according to a table of test results and other information published on the agency’s antimicrobial testing website June 12. The reviews could result in requiring registrants to reformulate their products, reduce their product claims, change their use directions, or cancel the products, EPA said. Products Could be Recalled. Representative of the Antimicrobial Division of the EPA Office of Pesticides Programs will discuss the implication of this report, and answer questions from the health care community.

EPA’s Office of Pesticide Programs (OPP) has the responsibility under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) to regulate the registration of antimicrobial products used to control pathogenic bacteria, viruses and other microorganisms for a variety of uses. Under FIFRA, the registrant of a product with a public health claim is required to submit efficacy, or effectiveness, data to EPA in support of the product’s registration. EPA reviews the effectiveness data as part of the registration process for each product. If the data meet efficacy standards and all other requirements for registration are met, the product qualifies for registration and is issued a distinct identification number, or EPA registration number, that appears on the product’s label along with other required statements.
