Some processed meat products recalled over concerns about possible Listeria bacteria contamination may have been sold at some retail outlets, Canada's food safety regulators said on Friday.

"Due to [a] misunderstanding, some independent stores may not have removed the recalled products as was intended," the Canadian Food Inspection Agency said in a statement Friday night.

The roast beef and corned beef products were part of a recall by Winnipeg food processor Smith's Quality Meats, which voluntarily recalled some of its meats earlier this month.

"These products may have been sold from deli counters at the customer's request or used in products such as sandwiches and cold cut trays produced and sold from the stores," the CFIA said.

The agency said consumers who cannot identify the brand of roast beef or corned beef recently purchased from independent stores should check with those stores to ensure that they are not using recalled meat.

There have been no reports of any illnesses associated with the products.

The meat was distributed in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario and all three territories, the agency said. The stores involved were supplied by MacDonald Consolidated.

In 2008, 22 people across Canada died after eating Maple Leaf Foods deli meats contaminated with Listeria.
