    • Abstract:
      Insufficient cleaning can create reservoirs of microorganisms, resulting in the spread of infection in the workplace. In this study, we examined the effects of increased cleaning of high-frequency touch sites on bioburden and absence rates at an office building. Daily cleaning of computer keyboards, mice, and telephones was performed on one floor and compared with a control floor. Contact plate samples were taken weekly from keyboards and bacterial contamination was assessed over a 3-month period. Increased cleaning and bioburden were compared to employee absence rates. Increased cleaning reduced overall bioburden on keyboards from 27-44 CFU/25 cm² to 7-11 CFU/25 cm² (n = 550), when compared with standard practice. Keyboards were found, however, to be recontaminated once used. Levels of bacteria from control floors decreased over the intervention period. Skin flora was most commonly isolated. Isolation of Enterococcus spp., suggesting fecal contamination, was reduced after increased cleaning. Regular cleaning reduces bioburden and has a lasting effect. Despite efficacy of increased cleaning, there was no significant effect on absences due to the wide variability of absence rates over time.
