Think the dust created by your vacuum only contains harmless hair and dust bunnies? A new study suggests more nefarious organisms could be lurking.

 

The study, published in the journal Applied and Environmental Microbiology, shows that mold and bacteria — with some bacteria even carrying antibiotic resistance genes, as well as the Clostridium botulinum toxin gene — are present in aerosolized vacuum dust. The study was conducted by researchers at the University of Queensland, the Universitaire de Cardiologie et de Pneumologie de Quebec, and the Universite Laval.

 

“Human skin and hair have been shown to be strong sources of bacteria in floor dust and air indoors, which can be readily resuspended and inhaled,” the researchers wrote in the study. “Our results show that although vacuum operation is typically brief, vacuum emissions can release appreciable quantities of human-derived bacteria. Such emissions could potentially lead to inhalation of infectious or allergenic aerosols.”

 

While researchers did not actually show in the study that the bacteria and mold in the vacuum dust caused health problems, they noted it does illustrate the “potential capability of vacuum cleaners to disseminate appreciable quantities of molds and human-associated bacteria indoors and their role as a source of exposure to bioaerosols.” Read More
