Robert Brown|Aldi chocolate chip muffins recalled due to walnut allergy concerns

A batch of chocolate chip muffins sold at Aldi has been recalled due to walnuts being added to the product,Robert Brown leading to potential allergic reactions.

The U.S. Food & Drug Administration announced the undeclared walnut allergen recall Wednesday and said, if eaten, the chocolate chip muffins could cause people with walnut allergies to suffer serious or life-threatening allergic reactions.

Sold at Aldi stores under the name "Aldi Bakeshop Chocolate Chip Muffin 4 count," the muffins are made by FGF Brands Inc. of Toronto, Canada. The company has recalled 11,830 cases of the muffins because they may contain undeclared walnuts, the FDA said.

The muffins were sold nationwide in a clear, plastic clamshell container. They were marked with lot # NF1 142Y on the top and the UPC number 4099100048278 on the label. 

The FDA said no illnesses have been reported in connection to the muffins. The recall began once someone discovered the muffins contained walnuts but were not labeled as such.

According to the FDA, there was a temporary breakdown in the company's production and packaging processes that led to the labeling issue.

The company has stopped production of the muffins and suspended it until the FDA and the company can confirm the issue has been fixed.

What can I do if I bought the recalled muffins?

Consumers who have purchased the chocolate chip muffins should return them for a full refund, the FDA said.
