Health warning issued for Lake Okaro


Health warning issued for Lake Okaro

A health warning has been issued for Lake Okaro near Rotorua as there are currently high levels of potentially toxic blue-green algae in the lake.

These algae are capable of producing harmful toxins at any time. Exposure to the toxins through skin contact or swallowing the affected water can result in significant symptoms including an acute asthma attack, skin rashes, vomiting and diarrhoea, tingling and numbness, or difficulty with breathing.

“People are advised to avoid recreational activities involving contact with the lake water,” says Dr Neil de Wet, Medical Officer of Health.

Lake Okaro, near Rainbow Mountain, twenty-five kilometres to the south of Rotorua, has a significant recent history of algal blooms reflecting the high level of nutrients contained in the lake sediment.
