Recent research carried out by the scientists from Florida Atlantic University found that 95% of 20 different smartwatch and fitness tracker wristbands tested were contaminated with potentially pathogenic species of Staphylococcus, Enterobacteria (like Escherichia coli), and Pseudomonas, capable of causing disease.
The researchers report that rubber and plastic bands had the most bacteria on them, while the metal bands tested (especially gold and silver) were nearly free from bacteria.
Biological scientist Nwadiuto Esiobu from Florida Atlantic University says: “The quantity and taxonomy of bacteria we found on the wristbands show that there is a need for regular sanitation of these surfaces. Even at relatively low numbers these pathogens are of public health significance.”
