More than 600 frozen waffle products sold at major stores were recalled Friday over fears of possible Listeria contamination.

TreeHouse Foods (THS-2.14%), which makes a variety of frozen waffle products for companies like Walmart (WMT-0.19%) and target (TGT-3.06%), which are often labeled under retailers' private brands, said the recall was voluntary and there had been no reports of illness.

“This issue was discovered through routine testing at our manufacturing facility in Brantford, Ontario, Canada.” the company said.

Affected brands include Always Save, Best Choice, Clover Valley, Food Lion, Good & Gather, Great Value, Hannaford, Harris Teeter (KR+0.23%), Kodiak Cakes, Higher Harvest by HEB, PICS by Price Chopper, Publix, Schnucks, Tops and others. A full list of recalled waffles can be viewed on TreeHouse website.

Listeria can cause fatal infections in children and the elderly, causing serious symptoms such as fever, headache, abdominal pain and diarrhea.

Treehouse said consumers should check their freezers for the products and either throw them away or return them for credit. It is working with the Food and Drug Administration and the Canadian Food Inspection Agency to address the issue.

The company also said its Brantford facility is “undergoing all necessary protocols, including deep cleaning, sanitation, hygienic recovery procedures and review of these activities to confirm effectiveness before we resume production and deliveries from this line.”
