According to Food Safety News, Canadian officials say an E. coli outbreak linked to romaine lettuce from Arizona has ended with eight confirmed cases in their country. The eight victims in Canada all reported eating chopped romaine lettuce in the days before becoming sick. They all said the romaine was in packaged salads from grocery stores or in salads from restaurants. Two of the Canadians reported traveling to the United States and eating romaine there before becoming ill. Canadians became sick between March 18 and April 22.
In Canada the investigation is officially over, according to the Public Health Agency of Canada.
