A health warning has been issued for Lake Rotorua due to the presence of a potentially toxic cyanobacteria or blue-green algae. The health warning is based on water test results and visual observations provided by the Bay of Plenty Regional Council which indicate blue-green algal blooms are affecting significant parts of Lake Rotorua.
Contact with water affected by blooms of blue-green algae can cause asthma and hayfever attacks in some individuals. Contact with the blue-green algae can also cause skin rashes, stomach upsets, and in some cases neurological effects such as tingling around the mouth, headaches, breathing difficulties and visual problems.
People and their pets should avoid contact with the water.
