Health warning to avoid blue-green algae during holiday weekend
Wisconsin health officials urge Fourth of July swimmers and boaters to avoid blue-green algae.
If you're going on a lake this Fourth of July, Wisconsin health officials say to watch out for blue-green algae.
State health officer Seth Foldy says there's a risk in touching or swallowing water with high levels of the algae.
And he warns people and pets to avoid swimming where the water looks like pea soup or paint.
