Chicken recalled after plastic, wood, metal found in food

Pilgrim's Pride announced that it is recalling more than 4.5 million pounds of fully cooked chicken products because they may be contaminated with "extraneous materials," according to the U.S. Department of Agriculture.

The USDA says the affected product comes in boxes of whole-grain breaded nuggets, patties, breakfast patties, tenderloins and popcorn-style varieties and were produced between Aug. 21, 2014, and March 1, 2016.

The recall was expanded by the Waco, Texas, company from a previous alert earlier this month. Its products were delivered nationwide to grocery stores and institutions like schools, according to CNN.

There's no clear answer yet as to the cause of the food recall and no injuries have yet been reported.
