Home Washing Machines Fail to Disinfect Healthcare Uniforms, Spreading Antibiotic Resistance
2025-04-30

A new study in PLOS One reveals that many home washing machines fail to effectively remove antibiotic-resistant bacteria from healthcare workers' uniforms, potentially contributing to hospital-acquired infections and antibiotic resistance. Researchers tested six home washing machine models, finding that half failed to disinfect clothing on a rapid cycle, and a third failed to adequately clean on a standard cycle. Potentially pathogenic bacteria and antibiotic resistance genes were also found inside washing machines. The findings suggest a need to revise laundry guidelines for healthcare workers or utilize on-site industrial laundry machines to improve patient safety and control the spread of antibiotic-resistant pathogens.
