More South Sound beaches have been closed to shellfish harvesting after tests have come back positive for diarrhetic shellfish poison, a biotoxin that makes food unsafe to eat, according to a news release.
The closure starts at Henderson Passage and continues northeast to Johnson Point, and then stretches south, covering all of Henderson Inlet.
Shellfish harvesting is prohibited on beaches along that shoreline.
Previous closures are still in effect at Squaxin Passage, along all of Budd Inlet and at Boston Harbor.
Never miss a local story.
Diarrhetic shellfish poisoning is a biotoxin that, if ingested, can cause nausea, vomiting, abdominal pain and diarrhea. Symptoms can begin 30 minutes to 12 hours after eating and feel similar to those of food poisoning, said Art Starry, Environmental Health Division Director for Thurston County Public Health and Social Services. Most symptoms will subside after 72 hours.
