(CNN) — Perdue Foods is recalling more than 31,000 pounds of ready-to-eat chicken products because they may be contaminated with pieces of “bone material.”

According to the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS), the fully-cooked chicken items were produced on March 21 and shipped to stores across the U.S.

The problem was discovered through consumer complaints. The service says “There have been no confirmed reports of adverse reactions.”

Perdue says the recall is being done “out of an abundance of caution.”

You can see the labels of the recalled products on the FSIS website.

The agency urges you to check your freezers for the recalled products and throw them away, or return them to the store you purchased them from.
