The investigation into the outbreak that started in mid-October (original notice) continues and health officials try to determine the source of the outbreak. Currently, poultry products are food items of interest; however, more evidence is required to definitely state this as the source.

Currently, the 91 cases have been reported from the following provinces: British Columbia (6), Alberta (11), Saskatchewan (2), Manitoba (2), Ontario (53), Quebec (13) Nova Scotia (2), Prince Edward Island (1) and New Brunswick (1). Individuals became sick between March 15 and November 30, 2015. The majority of cases (60%) are female, with an average age of 40 years. Sixteen people have been hospitalized, and all have recovered or are recovering. No deaths have been reported.

Salmonella is an organism that can cause foodborne illness in a person who eats a food item contaminated with it. Symptoms of infection may include fever and gastrointestinal symptoms such as nausea, diarrhea, vomiting or abnormal pain. The illness primarily impacts young children, frail and elderly people and those with weakened immune systems. Most healthy adults and children rarely become seriously ill.
