Care Homes

Nursing home residents are often high risk due to underlying illness and age and as such have a far greater susceptibility to contracting illnesses such as Legionella. Nursing homes also have multiple different types of water system and some of these can be little used due to the infirm nature of residents.

Most nursing homes have showers and these pose a greater risk due to the aerosol production and often water systems in nursing homes are fed from large water storage tanks to provide continuity of supply in the event of a mains water outage. It is therefore important to implement a rigorous Legionella management regime including a Legionella risk assessment and routine monitoring of outlet temperatures. Microbiological water sampling can supplement this regime, giving confidence in its efficacy.
