The Food and Drug Administration has announced a recall of four varieties of frozen dinners over the possible presence of “wood-like” material in the entrees. The recall was initiated after customers contacted Nestle regarding the issue, which includes one potential choking incident to date.

The latest not-food-in-your-food recall pulls Lean Cuisine and Stouffer’s frozen meals from shelves at Walmart, Publix, Kroger, Kroger-owned chains and other grocers. As explained by Nestle USA’s recall notice, customers told Nestle about meals with “wood-like material,” and there has been “one potential choking incident” so far.
