Norovirus detected anew in BC oysters
Two oyster farms implicated in the latest norovirus outbreak have been closed by federal authorities.
The B.C. Centre for Disease Control says 40 cases of acute gastrointestinal illness have been reported to public health authorities since early March.
In late 2016 and early 2017, 347 norovirus outbreak cases associated with raw or undercooked oysters were reported in BC, Alberta and Ontario. That outbreak was declared over in April 2017.
