(WJW) – Bread sold in a dozen states has been recalled because the product may contain undeclared hazelnuts, according to a post from the U.S. Food and Drug Administration.

In a release shared by the FDA, Hartford Bakery, Inc. said it was recalling six lots of bread sold at popular retailers, including Kroger and Walmart.

“People with a nut allergy or severe sensitivity to hazelnuts run the risk of serious or life-threatening allergic reactions if they consume these products,” the recall reads.

Specifically, the recall affects about 883 12-ounce loaves of Lewis Bake Shop Artisan Style 1/2 Loaf with a UPC of 24126018152 on the bottom of the plastic bag it comes in. The bread has an expiration date of 07/13/2025, according to the company.

You’ll also see lot codes of T10 174010206, T10 174010306, T10 174010406, T10 174020206, T10 174020306, or T10 174020406 on the front of the packaging.

The artisan bread was sold at retailers, including Kroger and Walmart, in Alabama, Arkansas, Georgia, Illinois, Indiana, Kentucky, Michigan, Mississippi, Missouri, Ohio, Tennessee, and Wisconsin.

The release included the below photos of the bread.

According to the recall notice, while no major reports of injury or illness have surfaced, Hartford Bakery is “aware of one customer who experienced digestive discomfort after consumption.” Consumers also reported seeing the nuts in the bread before consuming it.

The company said the packaging warns the bread may contain tree nuts, but not that hazelnuts are present.

“An investigation revealed an error in change of packaging for a hazelnut-containing bread to the implicated white bread product,” Hartford Bakery explained.

If you have a loaf of the impacted bread, you should return it to the store for a full refund. Questions can be directed to Hartford Bakery by calling 1-812-425-4642 on weekdays from 8 a.m. to 3 p.m. CT.
