The Public Health Agency of Canada says two cases reported this month include a person in Manitoba and a person in Ontario and are linked to products sold by Canada Safeway Inc.
The Canadian Food Inspection Agency says the other fives cases are from December and include products sold by Loblaws.
These confirmed cases include four people in Ontario, two in Alberta and one in Manitoba.
The health agency says these people became ill in December and January and are now recovering.
Earlier this month the CFIA announced that Canada Safeway was recalling products including Gourmet Meat Shoppe Big & Juicy Burger and the Gourmet Meat Shoppe Prime Rib Burger with a best before date of Aug. 14.
Officials say the two most recent cases of E. coli are linked to recalled Gourmet Meat Shoppe Big and Juicy burgers.
The products were distributed in Ontario, Manitoba, Saskatchewan, Alberta, British Columbia and the Northwest Territories.
Also affected in the recall are Butcher's Cut Pure Beef Patties sold in packages of 10, 20 and 40.
The Public Health Agency Canada website says the risk to consumers remains low because all products found to be contaminated were recalled from store shelves.
The agency says people should check their freezers and either return or throw out any of the recalled products.
Recalled beef products from Loblaws in December included certain Butcher's Choice Beef Burgers.
