The BC Centre for Disease Control (BCCDC) is issuing a warning to the public after nearly 70 cases of stomach illness were discovered following the consumption of oysters from the province.
According to a news release from the BCCDC, 64 cases of norovirus-like gastrointestinal illness have been reported in Vancouver Coastal Health, Fraser Health, and the Island Health regions.
People who have been affected by the illness have reported symptoms like diarrhea, vomiting, and/or stomach pain after eating raw oysters from restaurants and some retail locations.
Some of the people who were experiencing these symptoms after consuming the BC oysters visited emergency departments, but no one has been officially admitted to the hospital.
“Norovirus is a common cause of gastrointestinal illness, especially during the winter months. Symptoms usually begin 12 to 48 hours after infection and can include nausea, vomiting, cramps, fever, and diarrhea,” reports the BCCDC.
It adds that fluid loss and dehydration could pose serious problems for very young people and older adults.
“Oysters can become contaminated with norovirus that may be present in the marine environment where they are grown and harvested.”
Food that’s contaminated with noroviruses might look, smell, or taste normal.
“To kill norovirus, you can cook oysters thoroughly to an internal temperature of 90 degrees Celsius for 90 seconds before eating.”
The BCCDC and the health authorities are investigating the reports with federal partners. It also offers some tips if you do contract a gastrointestinal illness, including using soap and water to clean your hands and not preparing food for others. It adds that most norovirus infections are mild and will pass after a few days.
“Dehydration is the most common complication. To prevent dehydration, drink plenty of fluids.”
There has been an increase in gastrointestinal illnesses after eating raw oysters from BC. We are reminding everyone about the risks of consuming raw or undercooked oysters. Cooking destroys viruses and bacteria and decreases the risk of illness: https://t.co/FIfvRQYGgX pic.twitter.com/TBv3p8kbcZ
