Taylor Shellfish's processing plant in Samish Bay.
(from Google Earth, 8/25/11)
Unlike fecal coliform, Vibrio parahaemolyticus (Vp) is a naturally occurring bacteria in Puget Sound. Unlike fecal coliform, every summer Vp numbers increase in the water column. Oysters and other shellfish then filter Vp from the water. If the shellfish are undercooked or eaten raw, it may cause vibriosis. In addition to Samish Bay, Vp has already caused Oakland Bay, Totten Inlet, Dabob Bay, and areas in Hood Canal.
Whether the apparent increase in outbreaks and significant closures are the result of an increase in Vp, additional monitoring, the increase of triploid (genetically modified) oysters which are more "edible" during summer, or a combination is not known.
For a report from August 23 listing all areas closed and why, see the Olympic Penninsula Environmental News here. It does not include the most recent Samish Bay closure but does include areas closed for other reasons (e.g., biotoxins).
