Pesticide News Story: EPA Seeks Efficacy Data for Antimicrobial Pesticides for Fogging or Misting

For Release: April 17, 2013

The EPA seeks to ensure that antimicrobial products that are intended to control public health microorganisms, and are applied by fogging or misting, are effective as claimed and are labeled in a manner that will prevent unreasonable adverse effects on human health or the environment. Registrants of antimicrobial products that contain fogger/mister label instructions are being asked either to provide existing efficacy data, or to commit to provide new data that address the public health claims for their fogger/mister products.

In a letter to registrants of these products (see link below), the EPA is asking that registrants submit for each product bearing fogging/misting application instructions, efficacy test data from their files regarding this use. If the efficacy data are not available, the EPA expects the company to provide new efficacy data using a protocol approved by the agency. When antimicrobial fogging/misting products were originally registered, data in support product efficacy for the use were not required to be submitted to the agency because the claims were not then considered to be public health related. The agency now considers the claims made for disinfection and sanitization products applied by fogging/misting to be public health related.

The agency intends to work closely with registrants to review existing data or to provide guidance on how to generate data to support public health-related claims. The EPA will allow reasonable timeframes for developing test protocols, conducting the studies and submitting them for EPA review. Some registrants have already submitted efficacy test protocols, which are under EPA review.

The EPA recognizes that there is a need for these fogging/misting products under many conditions where sanitization and disinfection are the desired effect. However, the agency has an ongoing responsibility to ensure that products applied by fogging/misting are effective.
