In the winter of 2017, Ontario was part of a large multi-provincial outbreak of Norovirus associated with consumption of oysters imported from British Columbia (BC). More than 300 cases including 145 clusters were identified in Ontario, BC and Alberta.
This was the first investigation in Ontario related to oysters, and there were a number of unique challenges that were encountered. This presentation provides an overview of the oyster industry and its unique features as they relate to outbreak investigations. We will also highlight the challenges faced in the 2017 investigation and how they were overcome.
By the end of this session, participants will be able to:
1. Understand pathogens and food safety issues involved in outbreaks involving oysters and other molluscs.
2. Describe how food safety investigations as a result of shellfish outbreaks differ from outbreaks due to other sources.
3. Describe at least two challenges involved with investigating norovirus foodborne outbreaks.
