Algae monitoring has started across the Bay of Plenty as Environment Bay of Plenty seeks to keep popular swimming holes free from potentially toxic algal blooms.
Direct exposure to the algae can cause skin rashes and stomach upsets. Hayfever and asthma may also be worsened.

In conjunction with Toi Te Ora – Public Health Service, Environment BOP will be monitoring main lakes and rivers throughout the summer and taking weekly records for signs of the blue-green algae. If significant blooms are found there will be specific health warnings issued.
Medical Officer of Health Dr Jim Miller says, 'Look before you leap; if the water looks discoloured, smells unusual, or if there is scum on the surface of lakes or on the beds of rivers, swim or play somewhere else.”
