For the past several months, UHL's Ankeny laboratory has tested hundreds of toys for the presence of lead. Exposure to high levels of lead is known to potentially cause neurological problems, particularly for young children.

Manufacturers have recalled many popular toys because of elevated levels of lead. Recalls are listed on the U.S. Consumer Product Safety Commission website at www.cpsc.gov. Hotlines operated by manufacturers include Mattel's recall hotline (800-916-4997) and RC2's toll-free line (866-725-4407), which is available between 8 a.m. and 5 p.m. Monday through Thursday and between 8 a.m. and 11 a.m. on Friday.
