Warnings go out for blue-green algae on Minnesota lakes
When the summer sun shines and temperatures climb, conditions are ripe for Minnesota lakes to produce harmful blue-green algae blooms.
Kelly O'Hara with the Minnesota Pollution Control Agency says "when in doubt, stay out." The blooms may contain toxins that can harm or kill pets and livestock. O'Hara says blue-green algae can also lead to skin and eye irritation, plus nausea and vomiting in humans.
The harmful blooms also have a bad odor. O'Hara says says blue-green algae are present in all Minnesota lakes in different amounts.
