Public warned after algal blooms detected on Mayo lakes
Mayo County Council has issued a public warning following reports of natural algal blooms and cyanobacteria along lake shorelines at Gortnorabbey, Lough Conn, and Callow Lake.
The recent spell of mild and calm weather has created ideal conditions for these blooms to develop, particularly along sheltered parts of the shoreline.
The council has cautioned that some of these blooms can produce toxins which may cause illness in humans and can be fatal to animals, especially dogs. The blooms often appear as green or blue-green streaks resembling paint on the water’s surface, or as silky scums along the edge of the lake.
Mayo County Council is liaising with the Environmental Protection Agency (EPA), local dog wardens, and the Department of Agriculture’s Veterinary Inspector regarding the situation.
Members of the public are being advised to take precautions where algal accumulations are visible:
•Avoid touching algal material on the shoreline.
•Wash hands thoroughly if contact occurs.
•Keep children and pets away from algae at the water’s edge.
•Do not allow pets to drink from the water. Giving dogs a good drink before walking near lakes or rivers can help prevent this.
•Wash pets immediately if they come into contact with potentially contaminated water.
If a dog becomes sick after swimming or contact with a suspected algal bloom, contact a vet immediately and, if possible, take photos of the algae at the location.
The council is reminding the public that vigilance is especially important during warm, calm weather, when algal blooms are more likely to develop.
