RED DEER COUNTY - Visitors to Pine Lake are being warned to take precautions after cyanobacteria, commonly known as blue-green algae was found in its waters this week.
Alberta Health Services issued an advisory for the Red Deer County lake Thursday, July 29.
“People who come in contact with visible cyanobacteria or who ingest water containing cyanobacteria may experience skin irritation, rash, sore throat, sore red eyes, swollen lips, fever, nausea and vomiting and/or diarrhea,” the advisory states.
Exposure to the bacteria may be fatal to pets, it adds.
AHS says cyanobacteria is naturally occurring and often becomes visible when weather conditions are calm.
Appearing like scum, grass clippings, fuzz or globs on the surface of water, cyanobacteria can be blue-green, greenish-brown, brown and/or pinkish-red, and often smell musty or grassy.
AHS advises visitors to the lake to take the following precautions:
• Avoid all contact with cyanobacterial blooms. If contact occurs, wash with tap water as soon as possible.
• Do not swim or wade or allow your pets to swim or wade in any areas where cyanobacteria is visible.
• Do not feed whole fish or fish trimmings from this lake to your pets.
• Consider limiting human consumption of whole fish and fish trimmings from Pine Lake, as it is known that fish may store toxins in their liver. People can safely consume fish fillets from this lake.
As always, AHS reminds visitors and residents to never drink or cook with untreated water directly from any recreational body of water, including Pine Lake, at any time.
“Boiling of this water will not remove the toxins produced by cyanobacteria. An alternate source of drinking water should also be provided for pets and livestock while this advisory is active,” the advisory states.
Weather and wind conditions can cause algae blooms to move from one location in the lake to another. As such, AHS says this advisory will remain in effect for Pine Lake until further notice.
Waters of Pine Lake in which the cyanobacterial bloom is not visible can still be used for recreational purposes, even while this health advisory is in place, AHS confirmed.
Anyone suspecting a problem related to cyanobacteria or requiring further information on health concerns and cyanobacteria is asked to call Health Link at 811. Additional information is also available online, at ahs.ca/bga.
“Symptoms usually appear within one to three hours and resolve in one to two days. Symptoms in children are often more pronounced; however, all humans are at risk of these symptoms,” the advisory says.
