Murray Regional Algal Coordinating Committee

New information on the blue-green algal bloom in the Murray River received today has shown an increase in algae numbers at Colignan through to Mildura.

Accordingly the Sunraysia Regional Algal Coordinating Committee has today issued a red alert for blue-green algae for the Murray River in this zone.

This bloom has now been confirmed as potentially toxic blue-green algae.Sunraysia RACC Chair, Owen Russell said that red alert indicates that waters are unsuitable for recreational use or primary contact by domestic users and may also pose a threat to livestock and domestic animals.

"The species of blue-green algae identified are potentially toxic and may cause gastroenteritis in humans if consumed and skin and eye irritations after contact, Mr Russell said.

Town water supply authorities are treating town water supplies with powdered activated carbon for Victorian consumers in Red Cliffs; however, raw water drawn from these areas should be avoided for all purposes.

"It is not unusual to have isolated blooms in the river at this time of year," Mr Russell said. Mr Russell reminded water users that a red alert continues for the Murray River from Hume Reservoir to Moama and also for the river at Swan Hill.

"The species of blue-green algae identified are potentially toxic and may cause gastroenteritis in humans if consumed and skin and eye irritations after contact. Boiling the water does not inactivate algal toxins," said Mr Russell.

"Many parts of the Murray River are still safe for recreational water-based and land-based activities and holiday makers are advised to check with the local tourism authority.

Information updates about blue-green algae blooms and red alert areas can be obtained from the Regional Algal Coordinating Committee freecall Algal Information Hotline on 1800 999 457 or visit www.water.nsw.gov.au
