Antimicrobial chemicals are used in many soaps and other personal-care products. They are found in household dust at concentrations comparable to those in wastewater. Laboratory studies have shown that these chemicals can promote antimicrobial resistance in aqueous environments. Hartmann et al. explore whether they are also associated with antimicrobial resistance in indoor dust. They report a positive association between antimicrobial concentration and the abundance of multiple antibiotic-resistant genes in indoor dust at a mixed-use athletic and educational facility. Antimicrobials may thus have a strong influence on the promotion and retention of antibiotic-resistant genes in indoor environments.
