The United States and Canada are investigating a multistate outbreak of norovirus illnesses linked to raw oysters from Canada.
Restaurants and retailers should not serve or sell these potentially contaminated raw oysters, which were harvested in the south and central parts of Baynes Sound, British Columbia, Canada, the U.S. Food and Drug Administration said.
The oysters were distributed in 13 states, but others may also have received them through further distribution within the United States, the FDA said.
