Shower heads accumulate scale, biofilm and sediment that create ideal conditions for Legionella growth and protect bacteria from disinfection. The fine aerosol produced by showers is directly inhaled, making contaminated shower heads one of the most significant Legionella exposure routes in care homes.
All shower heads and hoses in resident areas should be removed quarterly, descaled using an appropriate chemical descalant or by soaking in a suitable disinfectant (e.g. Milton or equivalent at the manufacturer's concentration), rinsed and refitted. This task should be carried out by a competent member of staff and the date and outlet recorded.
Flexible hoses are a reservoir for biofilm that cannot be adequately cleaned. Best practice is to replace flexible shower hoses annually rather than attempt to clean them. Mark each hose with the installation date using a tie-on label to track replacement.
