A recall affecting numerous frozen waffle products and other toaster items sold at various grocery stores across the United States has been broadened due to potential contamination with harmful listeria bacteria, as announced by the manufacturer on Tuesday.

TreeHouse Foods Inc., located in Oak Brook, Illinois, revealed that the expanded recall encompasses all items produced at a facility in Ontario, Canada, which are available at retailers such as Albertson’s, Aldi, Dollar General, Kroger, Publix, Target, Walmart, and several others. The recall specifically includes frozen toaster waffles, Belgian waffles, and pancakes, according to the company.

So far, there have been no reported illnesses connected to this recall.

TreeHouse Foods is collaborating with food safety authorities from both the U.S. and Canada to address the contamination issue. The recalled products are marketed under multiple brand names, including Walmart’s Great Value and Target’s Good & Gather. A full list of the affected items is available on the TreeHouse website. Consumers are advised to dispose of the products or return them to the point of purchase for a refund.

The initial recall was issued on October 18 after routine testing detected listeria at the manufacturing site in Brantford, Ontario. Subsequent testing suggested that additional production lines within the facility might also be compromised, prompting the company to halt production. They plan to resume operations only after implementing comprehensive measures such as deep cleaning, sanitation, hygienic restoration, and other procedures.

With 26 facilities operating in the U.S. and Canada dedicated to producing private label food and beverage items, the company stated that no other sites have been impacted.

Listeria infections can lead to a range of health issues, from mild symptoms like fever and diarrhea to severe complications. This illness poses a higher risk to certain groups, including pregnant women, newborns, elderly individuals, and those with weakened immune systems, as reported by the U.S. Centers for Disease Control and Prevention (CDC). Symptoms can take as long as 10 weeks to manifest.

The CDC estimates that approximately 1,600 individuals in the United States contract listeria each year, resulting in around 260 fatalities.

This incident marks the third significant recall in recent months concerning foods that may be tainted with listeria, a resilient bacteria known for being challenging to eliminate.

In July, Boar’s Head Provision Co. Inc. from Sarasota, Florida, initiated a recall of over 7 million pounds of deli meats, shutting down its plant in Jarratt, Virginia, following the discovery of listeria in their products, which were linked to at least 10 fatalities and nearly 50 hospitalizations.

Additionally, earlier this month, Oregon-based BrucePac recalled nearly 12 million pounds of meat and poultry processed at an Oklahoma facility after routine tests revealed the presence of listeria.
