KAWARTHA LAKES-The Ministry of Environment and Climate Change is warning residents not to use the water in areas of Lake Scugog after confirming the presence of blue green algae in the Port Perry area, in front of Palmer Park.
The Township of Scugog has posted the area of concern with support from the Durham Region Health Department.
Officials say the toxins released by blue-green algae when it is dying or disturbed can pose health risks for anyone using the water, including pets. Drinking the water may result in headaches, fever, diarrhea, abdominal pain, nausea and vomiting. Bathing or showering in the water can result in skin rashes, swollen lips, eye irritation and redness, ear ache and itchiness, sore throat, hay fever-like symptoms and asthma.

Anyone experiencing these symptoms should seek immediate medical attention.
Boiling the water will not help as the process just kills the algae resulting in the release of more toxins into the water.

Blue-green algae is also harmful to animals and has been known to cause death according to a release from Kawartha Conservation. Animals drink from the shorelines where algae tend to collect; therefore, they ingest large amounts of any toxins released. There have also been deaths reported in water-dwelling animals such as otters and waterfowl. Cattle are often highly impacted by the algae; however, there are not as many deaths due to the size of the animal. Fish can intake toxins from the algae as well, so when eating any fish caught in or near a water body affected by the algae, remove all the internal organs where any toxins would collect.
Officials say it is difficult to predict when and where a bloom will occur and for how long the toxin associated with the algae will be present, as environmental conditions continually change.
Blue-green algae occurs naturally during hot periods of weather in fresh water lakes and reservoirs with shallow, slow-moving, or still water that is rich in nutrients such as phosphorous and nitrogen. The algae thrive in areas high in nutrients, which can be elevated in lakes and streams due to human activities.
Some of the human sources of these nutrients include storm water runoff, fertilized lawns around the lake, shoreline erosion, industrial effluent, agricultural runoff, faulty septic systems, and sewage treatment plants.
Algae blooms, which can often give the water a pea soup appearance, can last up to three weeks and be pushed around the lake by the wind and currents.
If you suspect a blue-green algae bloom, assume toxins are present and call the Ministry of the Environment Spills Action Centre at 1-800-268-6060.
If you are unsure about the safety of water for drinking during an algae bloom the Ministry suggests you use alternative water sources such as bottled, carted or tanked water.
