The California-based consumer group GoodGuide raised concerns this weekend over the presence of a potentially harmful heavy metal in a Mr. Squiggles model of the robotic hamsters that it tested. The group said its testing found excessive levels of antimony, a heavy metal that can cause heart and lung problems, on the toy's hair and nose.
But the group said Monday that its testing method doesn't match federal testing standards and shouldn't be compared. And the CPSC quickly reached the conclusion that the toys, which retail for about $10, are safe.
"CPSC confirmed today that the popular Zhu Zhu toy is not out of compliance with the antimony or other heavy metal limits of the new U.S. mandatory toy standard," agency spokesman Scott Wolfson said.
