Salt Ponds Coalition And DEM Advise Charlestown Shellfish Free of Algal Toxins

DEM announced this week that the precautionary shellfish harvesting closure announced last week for Narragansett Bay, Mt. Hope Bay, Kickemuit River, Sakonnet River and their tributaries remains in effect until further notice. Water samples collected on Sunday, October 9 still show high levels of phytoplankton in the Bay.

Toxins are present in shellfish meats from the closed areas. The toxin, known as domoic acid, produced by these phytoplankton is responsible for causing amnesiac shellfish poisoning (ASP) in humans. Symptoms of ASP include short- and long-term memory loss along with other serious health effects.

According to the Salt Ponds Coalition, Charlestown’s Salt Ponds have tested clear by R.I. Department of Environmental Management (DEM) and the R.I. Department of Health.
