Samples taken at Moonlight Beach and Main Beach tested positive for the toxic bacteria
Results from samples taken July 17, 2014 from Moonlight Beach and July 19, 2014 from Main Beach on Ramsey Lake are positive for blue-green algae.
Blue-green algae can rapidly increase in warm, undisturbed surface water that receives a lot of sunlight. When this occurs, they can form blooms that discolour the water or produce floating rafts of scum on the surface of the water. Blue-green algae can be harmful to health in high quantities.
At high enough levels, the algae toxins can irritate a person’s skin and, if ingested, cause diarrhea and vomiting. If a person ingests large amounts of toxin, they could suffer liver and nervous system damage.
The highest concentrations of toxins are usually found in blooms and scum on the shoreline. These dense accumulations pose the greatest potential risks to people and pets.
The health unit advises people a avoid using water from a blue-green algae bloom for drinking, bathing or showering.
Shallow drinking water intake pipes can pump in blue-green algae.
Boiling water with blue-green algae, or treating it with a disinfectant like bleach, only breaks open the algae cells and releases more toxins into the water.
Water filtration systems also may not protect against the toxins from the algae.
Residents should not eat the liver, kidneys, and other organs of fish caught in water with blue-green algae.
Blue-green algae was previously confirmed in Ramsey Lake in September of 2013.
