A dozen years of norovirus outbreaks in oysters

Shellfish are filter feeders, meaning they filter seawater through their bodies to get food floating in the water. When norovirus particles are in the water, shellfish can accumulate the virus in their bodies.

There have been several BC oyster recalls since mid-March. The illness in Canada began in mid-January. Illnesses in Seattle and Minnesota began in mid-March. 279 with Norovirus in Canada, 29 with Norovirus in Minnesota and 27 with Norovirus in Seattle. Minnesota health officials said they are working with “federal officials and public health agencies in other states and Canada to investigate norovirus illnesses associated with oysters.”
