THUNDER BAY — It's shaping up to be another significant season for confirmed cases of blue-green algae, with the majority occurring in waterways a short drive from Thunder Bay.
The latest case was confirmed in Kenogamisis Lake's Barton Bay near Geraldton, according to the Thunder Bay District Health Unit.
The health unit said on Tuesday the case was based on a water sample that was taken from the bay on Sept. 16.
So far this season, there have been seven confirmed cases — one fewer than in 2023 within the health unit's jurisdiction.
Blue-green algae, which usually appears as a green slime on the water's surface, can be toxic to humans and animals.
Waterways that have been impacted should be avoided for at least two weeks after sightings have dissipated, health officials advise.
The number of cases has been on the rise in recent years due to warming temperatures and phosphate discharges from household appliances.
Suspected sightings can be reported to the province's Spills Action Centre at 1-800-268-6060.
