Toxic algae closes lake to swimmers

A toxic algae infestation has prompted a health warning for Lake Tutira, north of Napier.

Hawke's Bay District Health Board said exposure to the blue-green algae (cyanobacteria) could cause severe skin rashes, stomach upsets and could spark hay fever and asthma attacks.

Medical officer of health Caroline McElnay said warning signs were being erected at the lake.

Dr McElnay said anyone affected by the algae should contact a doctor - but there was no treatment other than to manage the symptoms.
