Those with allergies or sensitive to milk or soy are at risk of suffering from a life-threatening reaction if they consume a particular brand of gravy. An estimated 500 cases of Heinz HomeStyle Bistro Au Jus Gravy was voluntarily recalled Saturday following incorrect labeling. The items have been mislabeled as "Pork Gravy" and do not display that the contents inside the jar contain milk and soy.

Consumers affected are those in possession of the Heinz HomeStyle Gravy Pork packed in 12-ounce glass with the Best By date that reads 12/28/2017 MU6F04 4Q with the UPC Code of 013000798907.

Customers looking for a full refund should return the product back to the place of purchase where they will also have the option to exchange the gravy. Customers can also get a full refund by calling 866-575-3808 between 9 a.m. to 6 p.m. ET, Monday through Friday.

The eight foods that represent 90 percent of allergic reactions in the United States are fish, soy, milk, eggs, peanuts, wheat, tree nuts and crustacean shellfish, the Centers for Disease Control and Prevention reported.

A food allergy is a result of the immune system identifying a food protein as an allergen and attacks it, Food Allergy Research and Education reported. Mild symptoms of food allergies can include nausea, stomach pain, hives, itchy mouth, sneezing and more. Whereas severe symptoms can include anaphylaxis, chest pains, shortness of breath, trouble swallowing and worse.

Kraft Heinz issued an apology along with the recall. "We deeply regret this situation and apologize to any consumers we have disappointed," read the statement.
