Stew Leonard's says it has recalled its chocolate chunk banana bread because it may contain undeclared walnuts.

Store officials say 39 packages were sold in the bakery department only at the Danbury location between Sept. 26 and Oct. 2.

The recall was issued after a customer discovered that a loaf contained walnuts, even though the ingredient was not listed on the label.

So far, no illness have been reported.

Customers who have purchased the bread are urged to throw it out or bring it back to the store for a full refund.
