Public health officials on Vancouver Island, off Canada’s Pacific Coast, suspect that the likely source of a norovirus outbreak associated with the March herring run was from untreated sewage associated with marine operations.
Untreated sewage also was blamed for shellfish farm closures in Baynes Sound this year.
But the Public Health Agency of Canada, working with provincial public health partners in investigating the Norovirus outbreak, noted that the precise cause of the contamination has not been identified.
“There are a number of potential risk factors, one of which is the herring fleet in Deep Bay,” said Greg Thomas, executive director of the Herring Conservation and Research Society.
