Download Risk Profile Update: Norovirus in bivalve molluscan shellfish (raw)

This report reviews if the risk from norovirus in bivalve molluscan shellfish (BMS) has changed since a 2009 risk profile. Norovirus testing of oysters has been an Imported Food Requirement since 2012. The lack of reported outbreaks suggests this measure is effective in leading to a decreased risk associated with BMS. The two most recent outbreaks were associated with recreational harvest of BMS, supporting that a risk remains here. Knowledge gaps have been identified to support future research.
