Two B.C. Vancouver Island oyster farms have been closed following an outbreak of norovirus associated with eating the raw shellfish.
The B.C. Centre for Disease Control says about 40 cases of acute gastrointestinal illness have been connected to the consumption of raw oysters since March. Testing has confirmed some of the cases were norovirus.
Federal officials with Fisheries and Oceans Canada (DFO) confirmed the affected farms are located on the east coast of Vancouver Island at Deep Bay and Denman Island.
While the two farms are no longer harvesting oysters for consumption, no recall of oysters has been issued by the Canadian Food Inspection Agency.
