(Newport, OR)  --  A number of norovirus cases are being linked to oysters produced in Yaquina Bay.  Oregon Oyster Farms in Newport is recalling oysters harvested in the bay after 17 people who ate raw oysters became ill earlier this month.  The Oregon Health Authority says those who got sick said they ate the oysters at restaurants in Lincoln County between February 12th and 14th.  Only one of the 17 was hospitalized, and all have since recovered.
