/CNW/ - Original Notice
Why you should take note
The United States
Centers for Disease Control and Prevention (U.S. CDC), the United States
Food and Drug Administration (U.S. FDA), and the United States
Food Safety and Inspection Service (U.S. FSIS) are investigating an outbreak of Escherichia coli
O157, commonly called E. coli,
that is linked to romaine lettuce coming from the Salinas, California
growing region in the United States
(U.S.). E. coli
can cause a serious, life-threatening illness.
Although an outbreak is not occurring in Canada
, the Public Health Agency of Canada
(PHAC) has identified one Canadian illness with a similar genetic fingerprint to illnesses reported in the U.S. investigation.
The Canadian Food Inspection Agency (CFIA) has confirmed that romaine lettuce from the affected areas reported in the U.S. investigation is imported to Canada
at this time of year. The CFIA has taken measures to protect consumers and is implementing new actions at the border to ensure that any affected romaine lettuce products are no longer being imported into Canada
As a result of the U.S. outbreak investigation and its link to product on the Canadian market, the Public Health Agency of Canada is advising Canadians to follow the U.S. CDC's public health advice, which advises consumers to not eat, and retailers and food service establishments to not sell or serve, any romaine lettuce harvested from the Salinas, California growing region in the U.S. Romaine lettuce harvested in Canada is not affected by this advice.
This is the fourth E. coli
outbreak linked to romaine lettuce affecting Canadian consumers in the last two years. The Government of Canada
, along with provincial and territorial governments and regional public health units, remains vigilant in its efforts to monitor for any new E. coli
illnesses linked to romaine lettuce. If future risks are identified, the Public Health Agency of Canada
and its partners will take the necessary steps to notify Canadians of any increased risk to their health and to provide updated advice on how to prevent illness.
At this time, there is no outbreak of E. coli
occurring in Canada
. The U.S. CDC is reporting multiple illnesses in several U.S. states. As of November 22, 2019
, there is one Canadian illness related to the U.S. outbreak that has been identified in the province of Manitoba
. This individual became ill in mid-October.
Laboratory analysis indicates that the illness reported in Canada
is also genetically related to illnesses reported in previous E. coli
outbreaks that occurred in 2017 and 2018 and were linked to romaine lettuce. This suggests that there may be a reoccurring source of contamination. Canadian and U.S. health officials are collaborating to identify commonalities between the recent illnesses in an effort to identify the source of contamination affecting consumers.
How does lettuce become contaminated with E. coli
are bacteria that live naturally in the intestines of cattle, poultry and other animals. A common source of E. coli
illness is raw fruits and vegetables that have come in contact with feces from infected animals. Leafy greens, such as lettuce, can become contaminated in the field by soil, water, animals or improperly composted manure. Lettuce can also be contaminated by bacteria during and after harvest from handling, storing and transporting the produce. Contamination in lettuce is also possible at the grocery store, in the refrigerator, or from counters and cutting boards through cross-contamination with harmful bacteria from raw meat, poultry or seafood. Most E. coli
strains are harmless to humans, but some varieties cause illness.
Who is most at risk
O157 is more likely than other E. coli
strains to cause severe illness. Pregnant women, those with weakened immune systems, young children and older adults are most at risk for developing serious complications.
Most people who become ill from an E. coli
infection will recover completely on their own. However, some people may have a more serious illness that requires hospital care, or long-lasting health effects. In rare cases, some individuals may develop life-threatening symptoms, including stroke, kidney failure and seizures, which could result in death. It is possible for some people to be infected with the bacteria and to not get sick or show any symptoms, but to still be able to spread the infection to others.
What you should do to protect your health
The U.S. CDC is advising that consumers not eat, and retailers and food service establishments not sell or serve, any romaine lettuce harvested from the Salinas, California
growing region in the U.S. Romaine lettuce harvested in Canada
is not affected by this advice.
Canadians are advised to follow the U.S CDC's advice and to check their homes for all types of romaine lettuce such as whole heads of romaine, hearts of romaine, and bags and boxes of precut lettuce and salad mixes that contain romaine, including baby romaine, spring mix, and Caesar salad.
- If you have romaine lettuce at home:
- If the packaging shows that it is from the Salinas, California growing region in the U.S., don't eat it. Throw it away.
- If it isn't labeled with a growing region, don't eat it. Throw it away.
- If you don't know whether the lettuce is romaine or whether a salad mix contains romaine, don't eat it. Throw it away. Wash and sanitize drawers or shelves in refrigerators where romaine lettuce was stored.
- If you buy romaine lettuce at a store:
- If the packaging shows that it is from the Salinas, California growing region in the U.S., don't buy it.
- If it is an unpackaged product, ask the retailer whether the romaine lettuce comes from the Salinas, California growing region in the U.S.
- If you can't confirm that the romaine lettuce in stores is not from the Salinas, California growing region in the U.S., don't buy it.
- Restaurants and retailers should check the label on bags or boxes of romaine lettuce, or ask their suppliers about the source of their romaine lettuce.
- Suppliers, distributors and others in the supply chain should not ship or sell romaine harvested in the Salinas, California growing region in the U.S.
People infected with E. coli
can have a wide range of symptoms. Some do not get sick at all, though they can still spread the infection to others. Others may feel as though they have a bad case of upset stomach. In some cases, individuals become seriously ill and must be hospitalized.
The following symptoms can appear within one to ten days after contact with the bacteria:
- mild fever
- severe stomach cramps
- watery or bloody diarrhea
Most symptoms end within five to ten days. There is no real treatment for E. coli
infections, other than monitoring the illness, providing comfort, and preventing dehydration through proper hydration and nutrition. People who develop complications may need further treatment, such as dialysis for kidney failure. You should contact your health care provider if symptoms persist.
What the Government of Canada is doing
The Government of Canada
is committed to food safety. The Public Health Agency of Canada
leads the human health investigation into an outbreak, and is in regular contact with its federal, provincial and territorial partners to monitor the situation and to collaborate on steps to address an outbreak.
provides food-related health risk assessments to determine whether the presence of a certain substance or microorganism poses a health risk to consumers.
The Canadian Food Inspection Agency conducts food safety investigations into the possible food source of an outbreak.
The Government of Canada
will continue to update Canadians as new information related to this investigation becomes available.
