(AP) - Reser's Fine Foods Inc. has voluntarily expanded a recall of packaged salads from its factory in Topeka, Kan.
The company based in Beaverton, Ore., said it took the step Saturday because the products distributed nationwide and in Canada may be contaminated with listeria, which can cause serious illness.
Symptoms of listeria include fever, headache, abdominal pain and diarrhea. People with weak immune systems, such as young children, elderly people and others can die. Pregnant woman can suffer miscarriage or stillbirth.
The recall was first announced Friday.
The company said in a statement on its website that there have been no confirmed illnesses linked to the products.
