Fogging and Misting Efficacy

Gas and vapor technologies are being used with fogging or misting devices to disinfect, sanitize or sterilize enclosed areas. Many of these systems are remarkably effective at decontaminating all the hard, non-porous surfaces within an enclosed room. The United States Environmental Protection Agency (EPA) sent a letter on April 1, 2013, notifying those antimicrobial product registrants with current registered antimicrobial pesticides that efficacy data must be provided to the EPA to support fogging or misting claims. Any new registrations must also submit efficacy data for claims using fogging or misting to disinfect, sanitize or sterilize rooms.

Accuratus Lab Services worked closely with EPA officials through a Pesticide Registration Improvement Act (PRIA) submission review in developing these protocols that have now been approved by the EPA. Having the protocols formally approved provides manufacturers with a faster and more economical solution to satisfying the new regulatory requirements. These EPA-approved protocols can be used to support the use of any type of fogging and misting device that registrants would like to include on their product label. Accuratus Lab Services has extensive experience working with antimicrobial pesticide fogging or misting products and has developed protocols for supporting efficacy label claims for bacterial disinfection, virucidal efficacy, efficacy against Clostridium difficile spores, tuberculocidal efficacy, non-food contact sanitization, and food contact sanitization.

Accuratus Lab Services has a dedicated fogging and misting testing room on site equipped with independent air handling and temperature control to perform this testing. Additional test rooms are available to meet manufacturers’ specific space requirements based on the device used in testing. This enclosed testing space can be configured to meet your product’s specific testing needs against a variety of bacteria, fungi, viruses or bacterial spores. We can help you develop a custom protocol, screen the product and complete the final GLP testing.
