For Release: August 28, 2019

Today, EPA released a Frequently Asked Questions web resource for the Series 810 – Product Performance Test Guidelines: Antimicrobial Efficacy Test Guidelines.

 The following three tests have been updated:

• 810.2000: General Considerations for Testing Public Health Antimicrobial Pesticides, Guide for Efficacy Testing[1]
• 810.2100: Sterilants, Sporicides, and Decontaminants, Guide for Efficacy Testing
• 810.2200: Disinfectants for Use on Environmental Surfaces, Guide for Efficacy Testing

The updated guidelines were initially posted in February 2018, with an implementation date of February 28, 2019. Since the publication of the three updated guidelines, EPA received numerous inquiries from stakeholders seeking clarification of several topics within the guidelines. In order to allow time to address stakeholder concerns, the agency delayed the February 28, 2019, implementation date for the updated guidelines by six months to August 28, 2019. In response to stakeholder requests, EPA has generated the Frequently Asked Questions Web resource to provide prompt and transparent guidance to all applicants regarding commonly asked questions concerning the updated 810 guidelines.

[1] The confirmatory data section in the 810.2000 test will be placed on hold pending new guidance that will be vetted through an additional public comment.
