The Canadian Food Inspection Agency is warning the public not to eat certain ham and cheese sandwiches made by Atlantic Prepared Food Ltd. of Prince Edward Island.
The agency says the affected sandwiches from the company in Alberton may be contaminated with Listeria.
The product, in a 185-gram package, has a best-before date of Dec. 6.
The packages are also marked with UPC 0 55742 98002 8 and a legend with establishment number 514.
The agency says the sandwiches were sold in Prince Edward Island and Nova Scotia and may have been distributed in other Atlantic provinces.
The company is voluntarily recalling the product, although there have been no reported illnesses associated with its consumption.
The product is sold in two types of packages: one is clear while the other includes a cardboard sleeve with the caption Sub Delicious.
The agency says food contaminated with Listeria monocytogenes may not look or smell spoiled.
However, consumption of food contaminated with this bacteria may cause listeriosis, which can cause high fever, severe headache, neck stiffness and nausea.
Pregnant women, the elderly and people with weakened immune systems are particularly at risk.
