"The problem was initially discovered on July 1, 2016, when an establishment employee observed metal fragments while dispensing sugar from a supplier for sauce formulation during processing. The resulting sauce is a component in the frozen entrée products. On July 14, 2016, ConAgra Foods was notified by the supplier of an FDA recall involving multiple production lots of sugar due to potential metal contamination. The recall action involved additional lots of sugar potentially used in FSIS regulated products at ConAgra Foods, and resulted in this expansion of the initial recall action."
There is no indication of whether there was an in-line metal detector or other control mechanisms for the entrée production or by the supplier for sugar production.
