Promising Carpet Disinfection Practices Against Clostridioides difficile Endospores

Disinfecting water-resistant nylon carpets with 120 seconds of steam and a specific hydrogen peroxide-based chemical reduced Clostridioides difficile (C. diff.) endospores more effectively than using only steam or other disinfecting chemicals or different carpets. An AHRQ-funded study in Applied and Environmental Microbiology tested how well two hydrogen peroxide- and one chlorine-based chemical removed C. diff. spores, a major source of healthcare-associated infections, from carpets with either water-permeable or waterproof backings. The efficacy of chemical disinfectants can be impacted by the types of carpet backings used in healthcare facilities. These findings are key to informing the development of floor disinfection strategies and the selection of carpet materials in healthcare facilities to improve microbial safety.
