Drakesbrook Weir closed for second time in weeks over potential risk of deadly amoeba in the water

A popular WA swimming spot has been closed for the second time this summer due to the potential presence of a deadly brain-eating amoeba.

The Shire of Waroona has been forced to close Drakesbrook Weir again after amoeba of the deadly naegleria fowleri was detected in water testing.

The shire detected the amoeba on Friday and is urgently warning the public against swimming in the popular spot.

It is the third time a swimming spot has been closed in the region this summer, with Brunswick Pool being closed for a period in early January.

The Department of Health has previously warned the amoeba thrives in warmer water and with the recent hot weather its presence is a possibility in any natural water source.

If thrust up the nose, the amoeba can cause a disease called amoebic meningitis, which caused inflammation and the destruction of brain tissue.

The Shire of Waroona is testing the water and will post results to the community as soon as they are available.

The council urges anyone who has recently submerged their head in Drakesbrook Weir and is feeling unwell or concerned to seek medical advice.
