The state is warning swimmers at a northwest Ohio park about potential hazards from toxic algae again appearing in Lake Erie's western basin.
The Columbus Dispatch reports noteworthy levels of a liver toxin produced by blue-green algae were found in recent water tests at Maumee Bay State Park, just east of Toledo. The warning recommends that older people, children and anyone with a compromised immune system avoiding swimming or wading in the area.
Warnings also have been posted at beaches at Grand Lake St. Marys in western Ohio, East Fork State Park near Cincinnati and Buckeye Lake in central Ohio.
The algae grow thick feeding on phosphorus in manure, sewage and fertilizers that rains wash into waterways. The algae produce toxins that can sicken people and kill pets.
