Residents are advised that a blue-green algae (BGA) bloom is currently affecting Lake Victoria in Maryborough.
This is likely due to lack rain and relatively warm weather late in the Autumn season.
The public is warned not to swim in and to avoid any direct contact with blue-green algae affected water.
People who come in contact with contaminated water should wash immediately in fresh water. Seek medical advice if experiencing illness after contact with BGA affected water.
People should not eat fish, or shellfish or crustaceans collected from Lake Victoria. The type of algae affecting Lake Victoria produces toxins that can concentrate in shellfish and crustaceans and accumulate in the liver and internal organs of fish. Ingesting BGA toxins can lead to serious illness.
Water from the affected water body should not be used for drinking, cooking or other domestic uses. Boiling the affected water will not make it safe for use.
For any health issues experienced after contact with BGA affected water, please seek medical advice immediately.
Pet owners should prevent pets from drinking or having direct contact with contaminated water.
Visitors to the area are advised that they can still enjoy other recreational activities such as walking and sightseeing around the water body.
For further information or to report any BGA related issues please contact the Environmental Health Team on 03 5461 0610.
