Contaminated shellfish can cause illness if eaten raw, particularly in people with compromised immune systems. Food contaminated with norovirus may look, smell, and taste normal. Consumers of these products who are experiencing symptoms of norovirus illness should contact their healthcare provider, who should report their symptoms to their local Health Department.

Summary of Problem and Scope

The U.S. Food and Drug Administration (FDA) is working with federal, state, and local officials, and with Canadian public health authorities on a norovirus outbreakExternal Link Disclaimer linked to raw oysters from British Columbia, Canada. Currently, illnesses have only been reported in Canada with no known cases of norovirus associated with these oysters reported in the U.S. The FDA is alerting restaurants, retailers and consumers because it is possible that states received these oysters through distribution to the U.S.

Retailers should not sell or serve raw oysters harvested from BC 14-8 landfiles #0278744, #0278742, #0278741, #0278740, #1414396, #0319716, #1414456, #1414457, #1400483, #1411206, #1407063, #1408485, #0278739, #0278737, #1403139, #0278734, #1411153 and #1411195, with harvest dates starting as early as January 16, 2023, which will be printed on product tags.

Shellfish can cause illness if eaten raw, particularly in people with compromised immune systems. Food contaminated with norovirus may look, smell, and taste normal.

FDA Actions

The FDA is issuing this alert advising consumers to not eat, and restaurants and food retailers to not sell, oysters harvested between January 16, 2023 and February 17, 2023, from BC 14-8 landfiles #0278744, #0278742, #0278741, #0278740, #1414396, #0319716, #1414456, #1414457, #1400483, #1411206, #1407063, #1408485, #0278739, #0278737, #1403139, #0278734, #1411153 and #1411195, British Columbia, Canada due to possible norovirus contamination. The FDA is awaiting information on distribution of the oysters and will continue to monitor the investigation and provide assistance to state authorities as needed.

Symptoms of Norovirus

People of all ages can get infected and sick with norovirus. The most common symptoms of norovirus are diarrhea, vomiting, nausea, and stomach pain. Other symptoms include fever, headache, and body ache.

A person usually develops symptoms 12 to 48 hours after being exposed to norovirus. Most people with norovirus illness get better within 1 to 3 days.

If you have norovirus illness, you can feel extremely ill, and vomit or have diarrhea many times a day. This can lead to dehydration, especially in young children, older adults, and people with other illnesses. Symptoms of dehydration include decrease in urination, dry mouth and throat, and feeling dizzy when standing up. Children who are dehydrated may cry with few or no tears and be unusually sleepy or fussy. 

If you think you or someone you are caring for is severely dehydrated, call your healthcare provider.

Recommendations for Restaurants and Retailers

Restaurants and retailers should not sell/serve the potentially contaminated oysters. Restaurants and retailers should dispose of any products by throwing them in the garbage or returning to their distributor for destruction.

Restaurants and retailers should also be aware that shellfish may be a source of pathogens and should control the potential for cross-contamination of food processing equipment and the food processing environment. They should follow the steps below:

  • Wash hands with warm water and soap following the cleaning and sanitation process.
  • Retailers, restaurants, and other food service operators who have processed and packaged any potentially contaminated products need to be concerned about cross-contamination of cutting surfaces and utensils through contact with the potentially contaminated products.
  • Retailers that have sold bulk product should clean and sanitize the containers used to hold the product.
  • Regular frequent cleaning and sanitizing of food contact surfaces and utensils used in food preparation may help to minimize the likelihood of cross-contamination.

Crohn’s disease is a chronic condition characterized by inflammation and irritation in the digestive tract. While it most commonly affects the small and large intestines, it can affect any part of the digestive tract.

Researchers estimate that over 500,000 people in the United States have Crohn’s disease. Studies also show that the condition has become more common in the U.S. and in Europe. 

The cause of Crohn’s disease remains unknown. Researchers previously found that a version of the norovirus that occurs in mice (MNV) causes cell death in panted cells – the cells that line the small intestine—with a specific gene deletion. 

Understanding more about how MNV triggers paneth cell death—a key marker of Crohn’s disease—could lead to new treatment strategies for the condition. 

Recently, researchers investigated how MNV might trigger Crohn’s disease in mouse models and human tissue samples. 

“Specifically, we identified a protective molecule called API5 that is normally released by special T cells, but that norovirus infection interferes with its release,” he added. 

The study was published in NatureTrusted Source.

As of ay June 10, 118 people have become sick with gastrointestinal illness on 16 separate river trips down the Colorado River in Grand Canyon National Park.

Most of the illness was reported in May, with no new cases reported since June 2.

Grand Canyon National Park has been monitoring the cases that have affected visitors on the Colorado River and also in the backcountry. 

A public health team (a collaboration among Grand Canyon National Park, the National Park Service Office of Public Health, Coconino County Health and Human Services, Arizona Department of Health Services and the Centers for Disease Control and Prevention) is currently working to address increased reports of gastrointestinal illnesses among river rafters and hikers, according to the park. 

A virtual town hall with river related stakeholders was held June 10. The public health team reviewed what is known about the GI illnesses, thanked the outfitters for their help and diligence and reached out for additional assistance with researching this outbreak.

The Public Health Agency of Canada (PHAC) is collaborating with provincial public health partners, the Canadian Food Inspection Agency (CFIA) and Health Canada to investigate an outbreak of norovirus and gastrointestinal illnesses involving four provinces: British Columbia, Alberta, Manitoba, and Ontario.

Investigation findings have identified consumption of spot prawns as the source of the outbreak. All of the individuals who became ill reported eating spot prawns before their illnesses occurred. More information is needed to determine how the spot prawns became contaminated with norovirus.

On May 31, 2022, the CFIA issued a food recall warning for several lot codes of live spot prawns that are associated with the illnesses under investigation. The recalled products have been sold in British Columbia, Alberta, Manitoba, and Ontario, and may have been distributed in other provinces and territories. The CFIA is continuing its food safety investigation, which may lead to the recall of other products. If other products are recalled, the CFIA will notify the public through updated food recall warnings.

Do not eat, use, sell or serve the recalled spot prawns. Check to see if you have the recalled spot prawns at home. If you do, throw them out and wash your hands.

The outbreak investigation is ongoing and additional actions to protect public health will be taken as needed. The public health notice will be updated as the investigation evolves.

As of June 1, 2022, there have been 48 cases of norovirus and gastrointestinal illness reported in the following provinces: British Columbia (11), Alberta (12), Manitoba (19), and Ontario (6). Individuals became sick between mid-May and late-May 2022, and no deaths have been reported. Although not all cases of illness have been tested, laboratory testing has confirmed the presence of a norovirus infection.

Mantab Inc. is recalling Below Zero brand whole, frozen raspberries because of possible norovirus contamination.

The recalled product has been sold in Quebec, Saskatchewan and Ontario.

Consumers, retailers, and restaurant owners should check to see if they have the recalled products in their homes or establishments. Recalled products should be thrown out or returned to the location where they were purchased.

The Public Health Agency of Canada collaborated with federal and provincial public health partners, the United States Centres for Disease Control and Prevention (U.S. CDC), and the U.S. Food and Drug Administration to investigate an outbreak of norovirus and gastrointestinal illnesses involving five provinces: British Columbia, Alberta, Saskatchewan, Manitoba and Ontario. The outbreak appears to be over and the outbreak investigation has been closed.

Investigation findings identified consumption of raw oysters from British Columbia as the source of the outbreak. As a result, some oyster harvesting areas in British Columbia that were associated with the outbreak were closed as a part of the investigation.

The Canadian Food Inspection Agency (CFIA) issued several food recalls throughout February, March, and April. Links to each food recall associated with this investigation can be found at the end of this public health notice.

The outbreak investigation is an important reminder to Canadians and businesses that raw oysters can carry harmful germs that can lead to foodborne illness if not properly handled and cooked prior to consuming.

In total, 339 confirmed cases of norovirus and gastrointestinal illness were reported in the following provinces: British Columbia (301), Alberta (3), Saskatchewan (1), Manitoba (15) and Ontario (19). Individuals became sick between mid-January and early April 2022, and no deaths were reported.

Some oyster harvest areas in British Columbia that were associated with illnesses in the outbreak were closed as a part of the investigation. The CFIA 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.

The U.S. CDC also investigated a multistate norovirus outbreak linked to raw oysters from British Columbia.

*This number is an estimate based on the information we have at this time. CDC is working with state and local partners to determine a more accurate number of illnesses in this outbreak and will update this number as more information is gathered.

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.

Seattle King County Department of Health added 10 linked to oysters served at Il Terrazzo Carmine.

California:  (34) The California Department of Public Health (CDPH) warned consumers April 2, 2022, not to eat raw oysters from British Columbia, Canada because they may be linked to an outbreak of norovirus illnesses in California. In California, at least 34 persons have become ill following the consumption of oysters at nine restaurants located throughout the state. Illness has been reported from March 11 through 19, 2022.

Minnesota: (29) On April 1, 2022, the Minnesota Department of Health, Hennepin County Public Health, and the Minnesota Department of Agriculture are working with federal officials and public health agencies in other states and Canada to investigate norovirus illnesses associated with oysters. 29 Minnesotans have been sickened in this outbreak. They became ill with confirmed or suspected norovirus gastroenteritis after eating raw oysters at Travail Kitchen in Robbinsdale on March 20.

Hawaii: (4) Hawaiian Health officials are warning the public of a norovirus outbreak linked to raw oysters from Canada that were distributed to restaurants and retailers in various U.S. states, including Hawaii, where several cases have been confirmed. The Hawaii Department of Health said as of late Tuesday, there have been four suspect cases of norovirus associated with raw oysters reported in the state. Three of the four suspect cases consumed raw oysters in Hawaii County, and one consumed raw oysters in Honolulu County, between March 8 and 22.

The Norovirus attorneys of Marler Clark have many years of experience working with clients on Norovirus outbreak lawsuits.

Noroviruses are estimated to cause 23 million cases of acute gastroenteritis (commonly called the “stomach flu”) in the U.S. each year, and are the leading cause of gastroenteritis. In addition, norovirus outbreaks may be the most common foodborne illness outbreaks. Noroviruses can cause extended outbreaks because of their high infectivity, persistence in the environment, resistance to common disinfectants, and difficulty in controlling their transmission through routine sanitary measures.

The norovirus is transmitted primarily through the fecal-oral route and fewer than 100 norovirus particles are said to be needed to cause infection. Transmission occurs either person-to-person or through contamination of food or water. Transmission can occur by:

· Touching surfaces or objects contaminated with norovirus and then placing that hand in your mouth

· Having direct contact with another person who is infected with norovirus and showing symptoms

· Sharing foods or eating utensils with someone who is ill

· Exposure to aerosolized vomit

· Consuming food contaminated by an infected food handler.

Acute gastrointestinal illnesses such as norovirus illness are common in North America and are very contagious, affecting all age groups. However, pregnant women, people with compromised immune systems, young children and the elderly are at risk for developing more serious complications, like dehydration.

People with norovirus illness usually develop symptoms of gastroenteritis within 24 to 48 hours, but symptoms can start as early as 12 hours after exposure. The illness often begins suddenly. Even after having the illness, you can still become re-infected by norovirus.

The main symptoms of norovirus illness are:

  • diarrhea
  • vomiting (children usually experience more vomiting than adults)
  • nausea
  • stomach cramps

Other symptoms may include:

  • low-grade fever
  • headache
  • chills
  • muscle aches
  • fatigue (a general sense of tiredness)

Most people feel better within one or two days, with symptoms resolving on their own, and experience no long-term health effects. As with any illness causing diarrhea or vomiting, people who are ill should drink plenty of liquids to replace lost body fluids and prevent dehydration. In severe cases, patients may need to be hospitalized and given fluids intravenously. If you have severe symptoms of norovirus, consult your healthcare provider.

The Public Health Agency of Canada is collaborating with federal and provincial public health partners to investigate an outbreak of norovirus and gastrointestinal illnesses involving four provinces: British Columbia (B.C.), Alberta, Saskatchewan and Ontario.

Based on the investigation findings to date, the outbreak is linked to consumption of raw oysters from B.C. Some oyster harvesting areas in B.C. that have been associated with illnesses in this outbreak have been closed as a part of the investigation. These closures aim to prevent further illness.

Food recalls were conducted on February 18, March 20, March 23, and March 27, 2022 for oysters from B.C. Links to each food recallassociated with this investigation can be found at the end of this public health notice. The Canadian Food Inspection Agency (CFIA) is continuing its food safety investigation, which may lead to the recall of other products. If other products are recalled, the CFIA will notify the public through updated food recall warnings.

Do not eat, use, sell, or serve the recalled oysters.

Also, avoid eating raw or undercooked oysters to reduce your risk of foodborne illness and follow proper food handling practices. Cook oysters to an internal temperature of 90° Celsius (194° Fahrenheit) for a minimum of 90 seconds.

The outbreak investigation is ongoing and additional actions to protect public health will be taken as needed. This public health notice will be updated as the investigation evolves.

Minnesota Area Norovirus Outbreak: The Minnesota Department of Health, Hennepin County Public Health, and the Minnesota Department of Agriculture are working with federal officials and public health agencies in other states and Canada to investigate norovirus illnesses associated with oysters harvested from Bay 14-8 in British Columbia.

Twenty-nine Minnesotans have been sickened in this outbreak. They became ill with confirmed or suspected norovirus gastroenteritis after eating raw oysters at Travail Kitchen in Robbinsdale on March 20. The oysters served were Stellar Bay Gold oysters harvested on March 10 from Deep Bay 14-8 CLF #140706 in British Columbia, Canada.

“Travail Kitchen quickly brought the cases to our attention, and immediately stopped serving oysters,” said Duane Hudson, Hennepin County Public Health, Environmental Health manager. “We are grateful to Travail for their help in protecting the public from foodborne illnesses.”

While some parts of the harvest area have been closed, it is likely that oysters from this area are still in the marketplace. With that in mind, officials are urging restaurants and distributors to check shellstock tags and discard oysters from this harvest area. Consumers can ask oyster suppliers or restaurants to check the shellstock tag for the harvest location. Norovirus and other pathogens found in raw oysters can be destroyed by cooking to 145 degrees Fahrenheit before eating.

Symptoms of norovirus typically include nausea, vomiting, diarrhea, or stomach cramps that begin 12 to 48 hours after ingestion of the virus. There is currently a high level of norovirus illness activity in Minnesota, and most is not associated with eating oysters.

“People with norovirus can spread it to others even after symptoms stop,” MDH Epidemiologist Supervisor Senior Carlota Medus said. “The best way to limit spread is to wash your hands well with soap and water after using the bathroom and before preparing food for others.”

Seattle Area Norovirus Outbreak: Public Health routinely reports the illnesses to Washington State Department of Health (DOH) Shellfish Program, which is responsible for tracking the harvest locations of the oysters implicated in these illnesses. Multiple illnesses tracked to a common growing area may result in the closure of implicated harvest locations or other enforcement actions.

We’ve recently received multiple reports of people getting sick with norovirus-like illness (nausea, vomiting, and diarrhea) after eating raw oysters in restaurants. In just March alone, we’ve received reports of 13 people whose illnesses we believe are linked to eating raw oysters. An additional 14 people became sick after being in close contact with the ill people who ate oysters. Most of the additional illnesses are among family members.

Eating raw oysters can make you sick because they can be contaminated with norovirus and other germs.  While norovirus is not typically a serious illness for healthy people, it can be very unpleasant. In addition, it’s highly contagious, meaning someone who has been infected with norovirus after eating raw oysters can easily pass the virus to their family and friends.
