PROVIDENCE, R.I. – Angelo Liberti, chief of the Rhode Island Department of Environmental Management (DEM) Office of Water Resources, and Ernest Julian, Chief of the Office of Food Protection at the Rhode Island Department of Health (RIDOH), will be available to answer questions today about the emergency shellfish closure in effect for major portions of Narragansett Bay.
WHO: Angelo Liberti, DEM | Ernest Julian, RIDOH WHAT: Media availability on emergency shellfish harvesting closure WHEN: Friday, October 7, 2016 – 1:30 p.m. WHERE: DEM Headquarters, 235 Promenade Street, Room 425, Providence
The shellfish closure is due to a confirmed harmful algae bloom (HAB) caused by the presence of toxic phytoplankton. This is the first HAB-related shellfishing closure in Rhode Island.
Impacted waters extend from the mouth of Narragansett Bay to Conimicut Point. This includes Narragansett Bay, Greenwich Bay, and all tributaries to those waters north of a line from the point just north of the Pettaquamscutt (Narrow) River at Cormorant Point to Beavertail Point in Jamestown to Brenton Point in Newport and south of a line from the Old Tower at Nayatt Point to the DEM range marker at Conimicut Point. At this time, the conditional areas of Mt. Hope Bay and the Kickemuit River are scheduled to reopen at noon on Saturday, October 8. The harvest restriction does not apply to carnivorous snails, such as whelk and moon snails.
DEM regularly monitors local waters for the presence of phytoplankton that can produce harmful algae blooms. Samples collected by DEM and tested by the State Health Laboratories at RIDOH yesterday confirmed a toxic bloom. Given the high concentrations of phytoplankton in several areas of Narragansett Bay and out of an abundance of caution, all portions of the Bay where these elevated levels were found are being closed to shellfish harvesting.
DEM, in partnership with RIDOH, has and will continue to collect local shellfish for analysis to determine if the toxins are present in shellfish meats at levels of concern. 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.
