Be leary of toxic blue-green algae at a South Portland, Maine park. News Center Maine is reporting that both of the ponds at Hinckley Park have a dangerous algae bloom known as cyanobacteria. South Portland Parks and Recreation confirmed on Monday that the bacteria is Oscillatoria, which is potentially deadly to dogs. It is dangerous for humans, too. Both ponds are closed; however, the park remains open.

On its Facebook page, South Portland Parks and Recreation shared pictures (below), and said the ponds will stay closed until later this year "when the water cools and the bloom dies off."

Symptoms include but are not limited to nausea, vomiting, sore throat, dermatitis and diarrhea, as per the Centers For Disease Control and Prevention. Read more about it here.
