The Public Health Agency of Canada said the unidentified person involved indicated he recently traveled to the United States.

The Canadian Food Inspection Agency said it is also monitoring the outbreak investigation related to Salmonella Saintpaul by the U.S. Food and Drug Administration. The outbreak might be associated with a food source, particularly certain types of uncooked, fresh tomatoes or products containing raw tomatoes.

"Consumers should be aware that tomatoes grown in Canada have not been implicated in the U.S. investigation," the CFIA said. "As there is no definitive link to a specific food source available in this country, no specific advice is being issued for people in Canada."
