An article in the Sept. 13 editions of The Sun about lead in children's toys said that an initial screening test performed at The Sun's request indicated that there might be lead in a LeapFrog Fridge Farm Magnetic Animal Set. That test, done with an X-ray fluorescence machine, is considered a screening test and is not definitive. When a more sophisticated chemical test was done, as the article reported, the toy was determined to be lead-free. The LeapFrog company says all such products it sells are designed and tested to exceed safety requirements.
