The Kitsap Public Health District announced a ban Friday on shellfish harvesting in Port Orchard Passage — from Agate Pass Bridge to Point Bolin.
Officials said the advisory will be in effect through Jan. 28, and was prompted by an illness investigation.
The closure area includes the west shoreline of Bainbridge Island.
All other existing shellfish closures remain in effect, the health district noted.
The ban covers all recreational shellfish, and shuts down harvesting for all species of clams, oysters, and mussels.
Shrimp and crab are not included in this closure, but officials note that crabs should be cleaned prior to cooking, and the “crab butter” should be discarded.
