About the Microbiology Laboratory

What We Do

The Microbiology Laboratory, under the Office of Pesticide Programs (OPP), is centered on the efficacy of antimicrobial products with public health claims that are registered by the EPA – products used to kill or suppress the growth of infectious microorganisms on inanimate objects and surfaces. Applied research on the evaluation and development of methods used to determine the efficacy of antimicrobials is a key priority. Recently, the laboratory has expanded its services to include, among others, major research in response to the anthrax attacks, and work on methods to identify genetically modified plant material.
