A naturally occurring poison on Tuesday led the state Departments of Environmental Management and Health to warn against recreational activities in, or drinking water or eating fish from several bodies of water in East Providence.

The poison, or toxin, resulted from a recent algae bloom in the Ten Mile River, Central Pond, Turner Reservoir and Omega Pond. The Ten Mile River originates in Massachusetts and forms the boundary between Massachusetts and Rhode Island along the northern half of East Providence and Seekonk; the other bodies of water are fully in East Providence.

People should avoid swimming, boating, or fishing in those areas until further notice, the agencies said in a news release. They said that a dense algae bloom has turned the waters of Turner Reservoir a bright green. The DEM, they said, has confirmed the cause is a blue-green algae, Microcystis — also referred to as cyanobacteria — that can form the naturally occurring toxin, Microcystin.
