Algae levels rise again in Metung area

19 January, 2012

Monitoring of blue-green algae in the Gippsland Lakes has detected concentrations of algae in the Metung area at levels that could adversely affect human and animal health on contact with the water.

Metung Marina, Tambo Bay, Chinamans Creek and Metung beach areas have all returned algal volumes above the health trigger levels for recreational waters, activating the re-installation of signs warning people to avoid contact with the water.

Regional Coordinator for the bloom response, Dr Daniel Mainville said while everyone was relieved to see the lower levels across most of the Lakes two weeks ago, it was always possible that they could rise again at any time over the summer period.

“This is why we’re conducting regular tests across the Lakes system, so we can immediately advise the public when levels rise above the point at which human health might be at risk,” he said.

Signs remain in place at Bunga Arm, Ocean Grange and Steamer Landing, where the levels of algae are still well above the trigger levels that can affect human health.

The Lakes Entrance, Eagle Point and Jones Bay areas and areas west of Paynesville currently remain at low levels and are safe for recreational water use. Lake Tyers remains free of blue-green algae.

Mussels, prawns and crabs caught anywhere in the Gippsland Lakes are not safe for human consumption. The signs warning people not to eat mussels, prawns or crabs caught in the Lakes will stay in place until testing shows that levels of the toxins in seafood have declined enough to lift the advisories.

The Department of Health advises that people can fish in the Lakes, but anglers are advised to remove and discard the gills and guts before cooking. Blue-green algae toxin concentrates in the internal organs of fish and fish should not be cooked whole as this will re-distribute toxins from the gut to the fish flesh, making it unsafe to eat.

Toxin levels in seafood will continue to be monitored. As soon as testing shows that seafood in affected areas is safe for human consumption the public will be informed.

The levels of algae in the water will also continue to be monitored on a regular basis and the public will continue to be informed about any changes in those levels.
