Vibriosis Closes Hammersley Inlet
Shellfish Growing Area
Over the past years, illnesses from oysters harvested from Hammersley Inlet have caused a variety of closures, some related to vibriosis, some related to noro-virus. Vibrio parahaemolyticus bacterium, the cause of vibriosis, occurs naturally in Puget Sound. As water temperatures rise it becomes more abundant. Because oysters are filter feeders, they retain this bacteria within their systems. If left in warm temperatures, the oyster becomes a petri dish which causes this species of bacterium to grow rapidly.
Food safety is important. The Department of Health does not recommend consuming raw oysters from south Puget Sound during the summer and instead suggests boiling, baking or broiling in order to kill any bacteria.
