Cyanobacteria health warning remains in place on Lakes Rotokaeo and Arapuni
National
Two health warnings remain in place for Lakes Rotokaeo and Arapuni. Cyanobacteria health warnings are also in place for Lakes Kainui, Arapuni Waikare and Ngā Roto.
The cyanobacteria concentrations in Lake Rotokaeo and Arapuni rose significantly leading to the latest public health warning and Medical Officer of Health, Dr Kate Meerkerk, said people should avoid any activity in or near the lake that could lead to skin contact with the affected water, or the water being swallowed.
“Toxins released by cyanobacteria can trigger asthma and hayfever symptoms, skin rashes, stomach upsets, and neurological effects such as tingling around the mouth, headaches, breathing difficulties and visual problems.”
The symptoms may not appear until sometime after contact with affected water.
Scums formed by algal blooms are a particular risk because they contain a high level of toxins. If contact with scum does occur, skin should be rinsed clean and clothing changed as soon as possible.
Parents are urged to keep a close watch on children near these lakes, and dog owners are cautioned to stop their pets from drinking or swimming in affected areas too.
If you feel unwell after coming in to contact with any of these lakes you should seek health advice from your doctor or by calling Healthline on 0800 611 116. Please also report it to the NPHS Waikato office on 07 838 2569.”
