Swimming spot in Western Australia tests deadly ‘brain-eating’ bug

A popular swimming hole has been tested for a deadly “brain-eating amoeba” as hot weather creates increased risks.

A species of organism closely related to a brain-eating amoeba has been found in a popular dam in Western Australia, sparking an urgent warning to swimmers.

Naegleria fowleri was detected in Drakesbrook Weir in Waroona, a small town 100km south of Perth, The West Australian reported.

The shire of Waroona announced the news after routine water checks and is now working to rule out the presence of the deadly naegleria fowleri - a brain infection that destroys brain tissue.

The dam was also closed in January and April this year due to similar risks.

The shire urged anyone who has recently been in the weir and was feeling unwell to visit a doctor.

Well facilitated with a grassy picnic area, a floating swimming platform and a freshwater beach, Drakesbrook Weir is a popular swimming spot for both locals of nearby Waroona and travellers given its proximity to the major state corridor, South Western Highway.

The amoeba thrives in warm, still water so as temperatures begin to rise, risk increases.

The shire has warning signs up to inform people of health risks.
