Boston’s Jamaica Pond closed due to potentially toxic algae

July 24, 2015

BOSTON (AP) — Health officials say Boston’s 68-acre Jamaica Pond has been closed because of algae blooms that can produce toxins and sicken humans and pets.

A Thursday news release from the Boston Public Health Commission says park visitors should not swim, fish, or boat on the pond and should avoid contact with the water or even any algae on shore. Dogs or other pets shouldn’t swim in or drink the water.

Exposure to the blue-green algae, also known as cyanobacteria, can cause skin, eye or respiratory irritation. If it’s producing toxins, the health effects can be more serious, especially for children and small pets.

Algae blooms can last for weeks or disappear quickly.

The state acceptable level is 70,000 cells per milliliter. Tests Monday had up to 81,576 cells per milliliter.
