CALERA, Okla. (KTEN) — A Calera woman alerted authorities after she said her granddaughter found pieces of glass in packaged snacks.

Nancy Jackson said her 11-year-old granddaughter found the shards in a package of Nachos Cheese Dip & Salsa Lunchables that were purchased at the Walmart in Durant.

Jackson said she found more glass after opening a second package.

Walmart said the products have been pulled from the shelves, and Jackson said she has filed a formal complaint with the Food and Drug Administration.
