\"Is<\/p>\n

Hospital-acquired infections are a major public health concern. This is in part because they frequently involve antibiotic-resistant bacteria. Many nurses and healthcare workers clean their uniforms at home in standard washing machines; however, according to a 2025 study<\/a> out of the UK, washing machine biofilms may harbour potential pathogens and antibiotic resistance genes, meaning home washing of healthcare worker uniforms may be unknowingly contributing to the spread of antibiotic-resistant infections in hospitals.<\/p>\n

With some studies having found that bacteria can be transmitted through clothing, the question that follows is whether these machines can sufficiently prevent the spread of dangerous microbes. To tackle this question, a research team \u2014 led by Katie Laird of the UK\u2019s De Montfort University \u2014 examined six models of home washing machine to evaluate whether they were successfully decontaminating healthcare worker uniforms.<\/p>\n

This evaluation involved washing contaminated fabric swatches in hot water, using a rapid or normal cycle. What was found is that half of the machines did not disinfect the clothing during a rapid cycle, while one-third failed to clean sufficiently during the standard cycle. Biofilms from inside 12 washing machines were also sampled, with DNA sequencing revealing the presence of potentially pathogenic bacteria and antibiotic resistance genes.<\/p>\n

Also shown through investigation was that bacteria can develop resistance to domestic detergent, something that increases bacterial resistance to certain antibiotics. What is suggested by these findings is that many home washing machines may be insufficient for decontaminating healthcare worker uniforms, and in fact may be contributing to the spread of hospital-acquired infections and antibiotic resistance. As such, the researchers argue that laundering guidelines given to healthcare workers should be revised.<\/p>\n

Such revision, the researchers say, should aim to ensure that home washing machines are cleaned effectively or, alternatively, that \u2014 to improve patient safety and control the spread of antibiotic-resistant pathogens \u2014 healthcare facilities should use onsite industrial machines to launder uniforms. \u201cOur research shows that domestic washing machines often fail to disinfect textiles, allowing antibiotic-resistant bacteria to survive,\u201d the researchers said.<\/p>\n

\u201cIf we\u2019re serious about transmission of infectious disease via textiles and tackling antimicrobial resistance, we must rethink how we launder what our healthcare workers wear.\u201d<\/p>\n
