(CNN) -- Packages containing frozen vegetables sold by Wal-Mart nationwide and Kroger stores in the Southeast may contain glass fragments, the supplier said Friday in announcing a voluntary recall.

While there have been no reports of injuries, the Pictsweet Co. of Bells, Tennessee, is advising the public not to eat the recalled store-brand vegetables because of the potential for harm.
