AHS warns of blue-green algae at Elk Island
Alberta Health Services (AHS) is warning visitors to Elk Island National Park of blue-green algae seen in the waters of Astotin Lake.
The health authority said to avoid all contact with blue-green algae blooms and to wash with tap water as soon as possible if contact occurs.
Do not swim or allow pets to swim or wade in areas where the algae is visible.
Consider limiting human consumption of whole fish or fish trimmings from the lake. Do not feed any fish or fish trimmings to pets.
Fish filets from the lake are safe for humans to eat.
Blue-green algae, also known as cyanobacteria, can look like scum, grass clippings, fuzz or globs on the surface water. It can be blue-green, greenish-brown, brown and/or pinkish-red, and often smell musty or grassy.

Skin irritation, rash, sore throat, sore red eyes, swollen lips, fever, nausea and vomiting and/or diarrhea can occur when exposed to blue-green algae or by consuming water containing the bacteria.
Exposure to blue-green algae can cause death to pets.
Waters of Astotin Lake that do not have visible blue-green algae can still be used for recreational purposes.
