Oyster beds in Plymouth, Kingston, Duxbury, and Marshfield are closed until further notice because a pathogen that can cause nausea, fever, and other ailments has been linked to those areas, state officials said Friday.
The pathogen, Vibrio parahaemolyticus, has been tied to oysters harvested in the beds, the state Department of Public Health and Division of Marine Fisheries said in a joint statement.
Officials said the shuttered beds are in Plymouth Harbor, Kingston Bay, Duxbury Bay, Bluefish River, and Back River.
Harvesting oysters in these areas is prohibited during the closure, and officials have launched a recall of oysters collected from the affected spots since July 22, according to the statement. Full story for BostonGlobe.com subscribers.
