Beau Sejour Leisure Centre has been closed with immediate effect after routine testing detected Legionella bacteria in its water system.

The centre shut on Tuesday 15 September and will remain closed on Wednesday 16 September while extensive investigations are carried out to identify the cause and conduct further testing.

Legionella bacteria can occasionally cause Legionnaires' Disease, a type of pneumonia that develops when contaminated water droplets are inhaled.

Preliminary results from routine precautionary testing were received on Monday 14 September afternoon, prompting staff to immediately shut down the showers. Further investigations led to the decision to close the entire facility.

The centre will not reopen until it is confirmed safe. Teams are working to find solutions to mitigate the impact on upcoming events, with officials hoping to reopen in time for the weekend.

Public Health has confirmed that they do not currently know of any cases of Legionnaires' Disease in the community. The bacteria cannot be passed from person to person.

The risk of illness to individuals remains low, and most people exposed do not become unwell. However, anyone who has used the showers at Beau Sejour in the last two weeks and develops symptoms should seek medical advice and mention that they might have been exposed to Legionella.

Symptoms of Legionnaires' Disease can include a high temperature or fever, a cough, shortness of breath or difficulty breathing, chest pain or discomfort, muscle aches, headache and, in some cases, confusion, tiredness or flu-like symptoms.

Symptoms usually develop between two and 14 days after exposure.

While anyone can develop Legionnaires' Disease, the risk is higher among older adults, smokers, and people with weakened immune systems or underlying lung disease.

The result was identified through routine precautionary testing of the centre's water systems, which is carried out regularly as part of ongoing health and safety measures.

Updates will be shared on States of Guernsey and Beau Sejour social media channels, with the next update expected on Wednesday afternoon.
