The Canadian Food Inspection Agency issued a recall notice Wednesday for 19 additional salads and dips produced by Reser's Fine Foods.
CFIA and Reser's are warning people not to eat the products, because they may be contaminated with listeria. No illnesses have been reported in association with the food.
Two previous recalls this month warned consumers about cheesy macaroni salad produced by Reser's.
The new recall includes a number of potato salads, macaroni salads, cole slaws, and creamy spinach dip. The products have best before dates ranging from Oct. 10 to Nov. 27. The products are also marketed under the brand name Market Pantry.
A complete list of the products, with UPC codes, is available on the CFIA web site.
Reser's is voluntarily recalling the products, and CFIA is monitoring the effectiveness of the recall.
Food contaminated with Listeria monocytogenes may not look or smell spoiled.
Symptoms of listeriosis include high fever, severe headache, neck stiffness and nausea. Pregnant women, the elderly and people with weakened immune systems are considered to be at higher risk.
