About Norovirus: Norovirus is a highly contagious virus and can be spread easily from person-to-person, through contaminated surfaces, and by eating contaminated food, including raw or undercooked oysters. Symptoms of norovirus usually begin 12 to 48 hours after a person has encounter the virus and can last for 1 to 3 days. Common symptoms include vomiting, diarrhea, nausea, and stomach cramps. People who develop symptoms of norovirus infection should consult their health care providers.  Also, see: What do you need to know about Norovirus and Raw Oysters.

Norovirus makes its way into the marine environment through untreated human sewage (poop) and vomit. This may come from leaky septic systems, faulty wastewater treatment plants, boaters, or beachgoers. Shellfish are filter feeders, which means 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.  For a bit of history: A Baker’s Dozen of years of Oyster Norovirus Outbreaks.

Some oyster harvest areas in British Columbia that have been associated with illnesses in this outbreak have been closed as a part of the investigation. The CFIA has issued several food recalls throughout February, March, and April. For more information on the recalled products, please consult the Government of Canada’s Recalls and Safety Alerts website.
