White Castle Original Sliders Recall for Undeclared Milk & Soy Allergens
Summary: White Castle Food Products LLC has voluntarily recalled two lot codes of its 4-count frozen Original Sliders after cartons were mistakenly filled with Jalapeño Cheese Sliders containing undeclared milk and soy. Customers with allergies should not consume the product and can obtain a full refund by following the steps below or calling 1-800-843-2728.
Reason for the White Castle Slider Recall
During production, some Jalapeño Cheese Sliders were packaged in cartons labeled “Original Sliders.” Because milk and soy are present in the Jalapeño Cheese recipe but not disclosed on the Original Slider label, people with milk or soy allergies risk a serious, potentially life-threatening reaction. One non-life-threatening allergic event prompted the investigation and nationwide recall.
