Heinz is recalling one of its gravy products just days before Thanksgiving due to a labeling issue.

Approximately 500 cases of Heinz HomeStyle Bistro Au Jus Gravy were mislabeled as Heinz Pork Gravy, WXIN reported.

This means that the product contains milk and soy ingredients not listed on the container, putting those with food allergies at risk.

People who are allergic to milk or soy run the risk of a serious or life-threatening allergic reaction if they eat the gravy, according to the FDA.

The affected containers were distributed all across the U.S.

To check if you have one of these mislabeled jars of gravy, WXIN advises:

Consumers should check 12 oz. jars labeled Heinz HomeStyle Gravy Pork with best by date of December 28, 2017 and a manufacturing code of MU6F04 4Q and a time stamp following the code. The jar’s UPC would be 013000798907.

For retailers, the box would be labeled Heinz HomeStyle Gravy Bistro Au Jus with a case best by date of December 28, 2017 and the code MU6F04. The case UPC is 10013000798508.

If you bought one of the mislabeled gravy jars, return it to the store where you purchased it for a refund or exchange.

The company is asking those with questions about the recall to call 1-866-572-3808, Monday through Friday, 9 a.m. to 6 p.m. Eastern.

Kraft Heinz recently closed one of its plants in Pennsylvania after 40 years of operation.
