The public is being asked to consider consuming other types of lettuce, instead of romaine lettuce, until more is known about an outbreak and the cause of contamination.
Currently, there are 40 cases of E. coli illness under investigation in five provinces: Ontario (8), Quebec (13), New Brunswick (5), Nova Scotia (1), and Newfoundland and Labrador (13).
Individuals became sick in November and early December 2017.
Sixteen individuals have been hospitalized and one person has died.
Individuals who became ill are between the ages of 4 and 85 years of age with 73% of them being female.
Individuals reported eating romaine lettuce at home, as well as in prepared salads purchased at grocery stores, restaurants and fast food chains.
The Canadian Food Inspection Agency is working with public health officials to determine the source of the romaine lettuce.
