Public Health Notice - Outbreak of Salmonella infections under investigation
OTTAWA, Oct. 19, 2018 /CNW/ - Original notice
Why you should take note
The Public Health Agency of Canada is collaborating with provincial public health partners, the Canadian Food Inspection Agency and Health Canada to investigate an outbreak of Salmonella infections involving five provinces: British Columbia, Alberta, Saskatchewan, Manitoba, and Quebec. The illness reported in Quebec was related to travel to British Columbia.
The source of the outbreak has not been identified and the investigation is ongoing. Outbreak investigators are gathering information on possible sources and possible ways contamination may have occurred. Many of the individuals who became sick reported eating cucumbers before their illness. However, other potential sources of illness are also being considered. More information is needed to determine the source of the outbreak. The outbreak appears to be ongoing, as illnesses continue to be reported.
Given the evolving nature of this outbreak, the Public Health Agency of Canada is issuing this public health notice to inform residents in western Canada of the investigation findings to date and to share important safe food handling practices to help prevent further Salmonella infections. At this time, there is no evidence to suggest that residents in central and eastern Canada are affected by this outbreak.
This public health notice will be updated on a regular basis as the investigation evolves.
Investigation summary
As of October 19, 2018, there have been 45 laboratory-confirmed cases of Salmonella Infantis illness investigated in the following provinces: British Columbia (37), Alberta (5), Saskatchewan (1), Manitoba (1), and Quebec (1). The individual from Quebec reported traveling to British Columbia before becoming ill. Individuals became sick between mid-June and late-September 2018. Nine individuals have been hospitalized. No deaths have been reported. Individuals who became ill are between 1 and 92 years of age. The majority of cases (58%) are female.
The Canadian Food Inspection Agency is conducting a food safety investigation. If contaminated food products are identified, they will take the necessary steps to protect the public, including recalling the product as required. Currently there are no Food Recall Warnings associated with this outbreak.
Who is most at risk
Anyone can become sick with a Salmonella infection, but infants, children, seniors and those with weakened immune systems are at higher risk of serious illness because their immune systems are fragile.
Most people who become ill from a Salmonella infection will recover fully after a few days. 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
It is difficult to know whether a product is contaminated with Salmonella because you can't see, smell or taste it. To help prevent Salmonella infections, the Public Health Agency of Canada recommends monitoring the outbreak investigation by checking for regular updates to this public health notice and following safe food handling tips. The following tips for preparing fresh fruits and vegetables may help reduce your risk of getting sick, but they may not fully eliminate the risk of illness.
- Wash your hands with soap and warm water for at least 20 seconds before and after handling fresh produce.
- Cut away any bruised or damaged areas on fresh produce, since harmful bacteria can thrive in these areas. Be sure to clean your knife with hot water and soap before using it again.
- Wash fresh produce thoroughly under fresh, cool, running water, even if you plan to peel them. This helps prevent the spread of any bacteria that may be present.
- Don't soak fresh produce in a sink full of water. It can become contaminated by bacteria in the sink.
- Use a clean produce brush to scrub items that have firm surfaces like cucumbers, oranges, melons, potatoes, carrots. It is not necessary to use produce cleansers to wash fresh fruits and vegetables.
- Use one cutting board for produce, and a separate one for raw meat, poultry, fish and seafood.
- Place peeled or cut fruits and vegetables on a separate clean plate or in a container to prevent them from becoming cross-contaminated.
- Use paper towels to wipe kitchen surfaces, or change dishcloths daily to avoid the risk of cross-contamination and the spread of bacteria, and avoid using sponges as they are harder to keep bacteria-free.
- Sanitize countertops, cutting boards and utensils before and after preparing food. Use a kitchen sanitizer (following the directions on the container) or a bleach solution (5 ml household bleach to 750 ml of water), and rinse with water.
Symptoms
Symptoms of a Salmonella infection, called salmonellosis, typically start six to 72 hours after exposure to Salmonella bacteria from an infected animal or contaminated product.
Symptoms include:
- fever
- chills
- diarrhea
- abdominal cramps
- headache
- nausea
- vomiting
These symptoms usually last for four to seven days. In healthy people, salmonellosis often clears up without treatment. In some cases, severe illness and hospitalization may occur. In some cases, antibiotics may be required. People who are infected with Salmonella bacteria can be infectious from several days to several weeks. People who experience symptoms, or who have underlying medical conditions, should contact their health care provider if they suspect they have a Salmonella infection.
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.
Health Canada 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 these investigations becomes available.
Epidemiological information
The figure below is an epi curve for this outbreak. This information is used by outbreak investigators to show when illnesses began, when they peak, and when they trail off. It can take several weeks from the time a person becomes ill to when this illness is reported and testing confirms a link to the outbreak. Data are available for 45 cases.
