There are three separate clusters of norovirus associated with raw oysters making people barf in the Vancouver area (that’s in Canada) but, as usual, no details were provided by health types on actual numbers of people sick.

CBC News reports the B.C. Centre for Disease Control has confirmed that an outbreak of illness related to eating uncooked Pacific Coast oysters is being caused by a norovirus.

The affected oysters have been traced to a section of Effingham Inlet on the west coast of Vancouver Island. The oysters were harvested between Sept. 7 and Sept. 21.
