Efficacy testing of disinfectants.
The U.S. Environmental Protection Agency's (EPA) Office of Pesticide Programs (OPP) has the responsibility for regulating antimicrobial products, including sporicides, used to treat and decontaminate inanimate surfaces. In response to the anthrax (Bacillus anthracis) attacks of 2001 and the associated need for verifying the performance of chemicals for building decontamination, the EPA initiated research in late 2003 to evaluate and improve efficacy test methods for sporicides. The OPP Microbiology Laboratory located at the Environmental Science Center, Ft. Meade, MD is the lead laboratory. Through funding provided by EPA's Office of Research and Development (Safe Buildings Program), a collaborative research plan has been established to address several key issues. Research is currently being conducted on 2 fronts: (1) the evaluation of quantitative methodology for assessing the efficacy of sporicides, and (2) the development and comparative testing of selected modifications to improve the AOAC Sporicidal Activity Test (AOAC Method 966.04). Future studies will include the evaluation of candidate surrogates of B. anthracis using a quantitative method, and a multilaboratory validation study of a quantitative method-surrogate combination. The General Referee is serving as the Principal Investigator for all research described in this report, and has the overall responsibility for the technical conduct of the projects. In cases where the General Referee has oversight of projects that involve official collaborative studies and validation support from AOAC INTERNATIONAL, AOAC officials and the Committee Chair will determine the appropriate mechanism for formal study review. The 2003 General Referee report provides the background on the development and direction of the research projects. The preliminary data, general conclusions, next steps, and recommendations are provided in this report.
