SOUTH BEND, Ind. -- The US Food and Drug Administration has announced a recall of bread that was sold in Indiana and Michigan that contain undisclosed amounts of a potential allergen.

Hartford Bakery, Inc. is voluntarily recalling six lots of its “Lewis Bake Shop Artisan Style 1/2 Loaf” as this product may contain hazelnuts," the FDA said late last week.

"Out of an abundance of caution, Hartford Bakery, Inc. is removing all units of product included in the six effected lot codes noted below. Hartford Bakery, Inc has determined that no other lot codes were affected," the recall stated. 

The recalled products were sent to stores in Michigan, Indiana, Wisconsin, Illinois, Ohio, Kentucky, Tennessee, Georgia, Arkansas, Missouri, Alabama, and Mississippi, including Kroger and Walmart.

The recall indicates the contaminated bread comes in a flexible plastic bag marked with Lot code T10 174010206, T10 174010306, T10 174010406, T10 174020206, T10 174020306, T10 174020406 on the front panel of packaging.

Net Weight 12OZ (340G), UPC 24126018152 found on the bottom of packaging.

An expiration date of 07/13/2025 found on the front panel of packaging.

The FDA says the recall was initiated after it was found that roughly 883 loaves of bread from six production lots contained visible hazelnuts and were distributed in “Lewis Bake Shop Artisan Style 1/2 Loaf” packaging.

While the packaging states “May Contain Tree Nuts,” it does not state that it “Contains Hazelnuts.”

"An investigation revealed an error in change of packaging for a hazelnut-containing bread to the implicated white bread product," the company said.

There have been no major reports of injury or illness, but the company is aware of one customer who experienced digestive discomfort after consumption. Hartford Bakery also received consumer complaints from those who saw the nuts before consuming the product.

Consumers who purchased the implicated products should return them to the place they bought them for a full refund.

Consumers with questions may contact Hartford Bakery at 1-812-425-4642 from 8 a.m. to 3 p.m. CST, Monday-Friday.
