Wet contact time directly impacts antimicrobial efficacy of Environmental Protection Agency–registered disinfectants

Published:December 04, 2018DOI:https://doi.org/10.1016/j.ajic.2018.10.005
      Routine use of disinfectants is recommended by the Centers for Disease Control and Prevention to prevent transmission of pathogens that may cause healthcare–associated infections.

      Although the Environmental Protection Agency (EPA) regulates the registration process of disinfectants, there are a number of key issues with disinfectant use that are not currently addressed by the Centers for Disease Control and Prevention or EPA guidance, which can lead to suboptimal performance of disinfectants. This article discusses the issue of inconsistent interpretation and practice of contact time specified on disinfectant labels.
