WASHINGTON -- Wal-Mart Stores is recalling about 220,000 Nu-Tronix brand karaoke cassette player/recorders.

The retailer says paint on the control buttons of the karaoke player contains excessive lead, posing a lead poisoning hazard to young children.

Lead poisoning in children is associated with behavioral problems, learning disabilities, hearing problems and growth retardation.

The recall includes the Nu-tronix Karaoke Cassette Player and Recorder with digital radio and alarm features.

A microphone with a white cord is attached to the cassette player.

The karaoke player is gray with a purple handle and a purple cassette cover. The karaoke player is sold with two cassette tapes with children’s songs, a multifunctional microphone and lyric sheets.

The recalled machines were sold at Wal-Mart stores nationwide from June 2003 through March 2005 for about $20.

Consumers should return the recalled karaoke players to their nearest Wal-Mart store to receive a refund.

Consumers can call Wal-Mart at (800) 925-6278 or can visit the retailer's Web site for more recall information.
