The study was designed to look at how effective disinfectants are when label directions are not followed exactly
Understanding the antimicrobial efficacy of disinfectants under different conditions offers healthcare facilities valuable information
Sealed Air’s Diversey Care division has released the first of a series of studies conducted with Purdue University, which focus on the bactericidal efficacy of disinfectants.
The research, expected to be published in the August 2017 issue of the American Journal of Infection Control (AJIC), determined that the three tested disinfectants were significantly less bactericidal at lower than label use contact times and concentrations.
“In busy healthcare facilities, disinfectants are often applied once and left to dry, regardless of the unique label instructions. As this study shows, disinfectants don’t live up to their claims if they get over diluted or are not reapplied as directed,” said Peter Teska, Infection Prevention Application Expert, Diversey Care.
“Choosing an Environmental Protection Agency-registered disinfectant and following label directions are key elements of effective disinfection and preventing the spread of healthcare-associated infections.”
Accelerated hydrogen peroxide (AHP), quaternary ammonium compounds (Quats) and sodium hypochlorite were each tested on stainless steel surfaces at room temperature (77°F) using EPA procedure MB-25-02. For each treatment, bacterial reduction was calculated, compared and analysed to find the following key results:
“Understanding the antimicrobial efficacy of disinfectants under different conditions offers healthcare facilities valuable information on disinfection limits, opportunities and corrective actions,” said Haley F. Oliver, Associate Professor, Department of Food Science, Purdue University.
