Derby City Vending of Louisville is recalling its Buffalo Chicken Sandwich because it may contain undeclared milk, egg and soy product. Those who have an allergy or severe sensitivity to milk, egg or soy run the risk of serious or life-threatening allergic reaction if they consume these products.

The Buffalo Chicken Sandwich was distributed to Kentucky and Indiana through delivery to vending food machines.

This product is in a black square container with a clear lid with the Derby City Vending label. It is identified on the label as Buffalo Chicken Sandwich with a best buy date of up to 12/4/16. No illnesses have been reported to date.

The recall was initiated after it was discovered through an inspection by the FDA that a product containing milk, eggs and soy was distributed in packaging that did not reveal the presence of these allergens. The problem was caused by a change in the ingredients by the manufacturer when a different size of the chicken patty was purchased.

No other Derby City Buffalo Chicken Sandwiches remain in production or have been distributed since this discrepancy was discovered.
