Algae Bloom Reported in Margaree Rivers

The Department of Environment is investigating reports that algae bloom found in Lake Ainslie, Inverness Co., is now in Southwest Margaree River and the Margaree River, in the same county.

Toxins produced by some algae can affect health. Water samples from the lake are being tested to determine if the algae is a type that emits toxins. Test results are expected to be completed within two weeks.

"People should not drink the water or use it to prepare or cook food, or to brush teeth," said the medical officer of health for the region, Dr. Richard Gould. "Boiling the water will not eliminate potential toxins."

Inspectors from the department are recommending to businesses that serve the public not to use water from the lake or rivers.

"Ingesting water containing toxins from algae can cause stomach ache, diarrhea, vomiting and nausea,” said Dr. Gould.

Swimming, bathing, showering with the water is not advised. Pets and livestock should not swim in, or drink, the water.

"Direct contact with toxins from algae can cause skin and eye irritation. The health risk is fairly low, but if symptoms persist after a few days, you should consult a physician," said Dr. Gould.

People should also avoid consuming the internal organs of fish taken from the lake or the rivers.

Algae blooms occur naturally in water that is high in nutrients such as phosphate and nitrate. The cause of the bloom is not known at this time.
