About 21,400 pounds of chicken, including some shipped to Minnesota retailers, is being recalled by a Wisconsin company because it may contain pieces of blue plastic, according to a USDA news release.

The 35-ounce packages of On-Cor frozen, microwaveable chicken patties were produced by OSI Industries on Aug. 5 and are labeled “P-5615” inside the USDA inspection mark. They bear a “best by” date of Aug. 5, 2017, and also were sent to stores in Kansas, Kentucky, North Carolina, Ohio and Wisconsin.

Three consumers have complained about blue plastic in their chicken, according to the release, though “there have been no confirmed reports of adverse reactions.”

The contamination happened around the time when “a trim repair was made on belt material,” the release said.

David Saltz, an OSI Industries spokesman, said he didn’t know how much was sent to Minnesota.

The patties should be thrown away or returned to the store, but not eaten.

The recall is considered Class II by the USDA, meaning there’s “a remote possibility of adverse health consequences from use of the product.”
