Results of EPA OIG’s Review of EPA’s Antimicrobial Testing Program
On September 19, 2016, the U.S. Environmental Protection Agency’s (EPA) Office of Inspector General (OIG) issued a report, EPA Needs a Risk-Based Strategy to Assure Continued Effectiveness of Hospital-Level Disinfectants, the result of OIG’s review of EPA’s Antimicrobial Testing Program (ATP) to “determine whether the program ensures the efficacy of EPA-registered hospital sterilants, disinfectants, and tuberculocides (“hospital-level disinfectants”); and to evaluate options for improving the ATP.” OIG found that the ATP “does not assure that hospital-level disinfectant products continue to be effective after they are registered,” specifically that:
Importantly, however, OIG concludes: “Although the program as currently designed and conducted does not assure that most hospital disinfectant products continue to be effective, at this point it is redundant and unnecessary to make adjustments, since the EPA is concurrently having the products re-registered.”
OIG makes two major recommendations:
In its response, EPA agreed with OIG’s recommendations, and stated it will develop a plan to coordinate and implement the discontinuation of the present-day program, with the closure of the ATP program to take place by November 2017. EPA also stated that by December 2018 it plans to develop a risk-based strategy to assure the effectiveness of public health pesticides used in hospital settings once products are in the marketplace.
Registrants of the affected products should monitor closely the development of EPA’s plans both to discontinue the program and to establish this new risk-based strategy for assuring product efficacy.
