Blue-Green Algae Is A Summertime Toxic Hazard For Pets

State health officials caution dog owners to be alert for toxic blue-green algae in Minnesota Lakes. Recently, dogs have died as a result from swimming in lakes containing blue-green algae. Lee Engel, Supervisor of Water Quality Monitoring Unit with the Minnesota Pollution Control Agency (MPCA), said every year during the mid-summer time, temperatures warm in lakes causing excess nutrient blooms. The algae can resemble pea soup, green paint or floating mats of scum. It can also have a bad smell. A dog recently died after exposure in Crawford Lake in Wright County. Another dog also became ill at Loon Lake near Waseca.
