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.
Meanwhile, the health warning that has been in place at Lake Rotoiti’s Okawa Bay has now been lifted after Bay of Plenty Regional Council testing and observations indicate the algal bloom in the area had now cleared.
However, a warning for Lake Rotoiti at the Okere Arm remains in place.
Dr Lane said: “People should avoid any activity which results in contact with the water in the Okere Arm of Lake Rotoiti.”
Signage advising potential lake users about algal blooms is erected at sites along the shore of the bay.
Lane warned people to keep an eye out for signs of algal blooms if using lakes in the area.
“Algal blooms can develop rapidly and unpredictably and can sometimes produce toxins that are harmful for people as well as animals. If the water looks discoloured, has an unusual smell, or has green or brown particles floating in it then it is best to avoid contact with it.”
