The Public Health Agency of Canada is collaborating with federal and provincial public health partners to investigate an outbreak of Salmonella infections in eight provinces. At this time, no source has been identified and the investigation is ongoing.
Salmonella bacteria are found naturally in the intestines of animals, reptiles and birds. The bacteria are most-often transmitted to people when they eat contaminated foods. Contaminated foods often come from animal sources, like poultry, beef, milk or eggs, but can also include fruits, vegetables, and herbs. Illness can be avoided if safe food handling, preparation, and cooking practices are closely followed.
Currently, there are 34 cases of Salmonella Infantis illness in eight provinces: British Columbia (3), Alberta (6), Saskatchewan (2), Manitoba (2), Ontario (16), Quebec (3) Nova Scotia (1), and New Brunswick (1). Individuals became sick between June 12 and September 20, 2015. The majority of cases (62%) are female, with an average age of 41 years. Eight people have been hospitalized, and all have recovered or are recovering. No deaths have been reported.
To date, the source of this investigation has not been identified, but the investigation is ongoing.
Symptoms of a Salmonella infection, called salmonellosis, typically start 6 to 72 hours after ingesting the bacteria.
Symptoms include:
- fever
- chills
- diarrhea
- abdominal cramps
- headache
- nausea
- vomiting
These symptoms usually last four to seven days. In healthy people, salmonellosis often clears up without treatment. In some cases, severe illness may occur and hospitalization may be required. People who are infected with Salmonella bacteria can be infectious from several days to several weeks. It is possible for some people to become infected with the bacteria and not get sick or show symptoms. Even though you don’t show symptoms, it is still possible to carry the bacteria and spread the infection to others. People who experience symptoms, or who have underlying medical conditions, should contact their health care providers if they suspect they have a Salmonella infection.
