A UK health trust has been fined for failing to control the risk to patients from exposure to legionella bacteria in its water systems. The hospital had water hygiene control measures in place, however they were unaware that the Annex where the legionella bacteria was found, was on a separate loop from the main hospital water system and not controlled appropriately.

The HSE investigation began following the death of a patient in their care from Legionnaires’ Disease. The legionella bacteria strain found within the hospital water systems was not the same bacteria strainĀ  as the one that caused the patient death, however the HSE concluded that there was sufficient evidence to prosecute the Trust for exposing patients to risks from its water systems.
