Tests carried out by Horizons Regional Council have shown elevated concentrations of cyanobacterial toxins (caused by blue-green algae) at Dudding Lake, near Marton, and a health warning has now been issued.
Visitors to the Lake are advised not to use the water body for recreational purposes until health warnings are removed.
Cyanobacteria produce toxins that are harmful to humans and animals if swallowed or through contact with skin (such as may occur when swimming, water skiing or kayaking).
Exposure to cyanobacteria may cause symptoms such as skin rashes, nausea, tummy upset and tingling and numbness around the mouth or tips of fingers.
