The south shores of Lake St. Clair are under a blue-green algae bloom advisory. The Windsor-Essex County Health Unit issued the warning on Friday, saying that people should avoid swimming if the water looks cloudy or like "green paint or pea soup." "Infants and young children [under age six] should not swim or play in the water. For adults and children six years of age and older, they should swim with caution and rinse off after swimming," the health unit said in a media release.
