OTTAWA—Various brands of pie and tart shells are being recalled due to the presence of E. coli.

The Canadian Food Inspection Agency says the shells are produced by Edmonton-based Harlan Bakeries and were sold across Canada.

The Deep Dish Pie Shells, Sweetened Tart Shells and Tart Shells are sold under the Great Value, Apple Valley, Western Family and No Name brands.

The CFIA says the best-before dates on the affected shells range from Nov. 24, 2017 to Dec. 21, 2017.

The federal agency says there have been no confirmed illnesses associated with these products.

Food contaminated with E. coli O121 may not look or smell spoiled but can still make you sick. Symptoms can include nausea, vomiting, mild to severe abdominal cramps and watery to bloody diarrhea.
