The Public Health Agency of Canada, in collaboration with other federal and provincial public health agencies, is investigating an outbreak of Salmonella Infantis infections of unknown origin that has affected people in eight provinces.
As of 13th November 51 cases had been identified across the country, with the province of Ontario being worst hit (26 cases). To date ten people have required hospital treatment, but all are recovering and there have been no reported deaths.
The source of the outbreak has not yet been identified, but the investigation is on-going. The fact that the cases are spread across such a wide area is consistent with the source being a single widely distributed food product, but this has not yet been confirmed.
