Hartford Bakery, Inc. is recalling about 883 loaves of its “Lewis Bake Shop Artisan Style 1/2 Loaf” bread because it may contain undeclared hazelnuts, posing a risk of severe allergic reactions for those with nut allergies.

The recall covers six production lots sold at retailers like Kroger and Walmart in 12 states.

No serious injuries have been reported, though one customer had digestive discomfort, CBS News has reported.

Affected products can be returned for a full refund.
