Cepia has said that the Mr Squiggles toy at the centre of the media frenzy has passed the most rigorous testing in the toy industry.
Russ Hornsby, chief executive officer of Cepia said: "We are disputing the findings of the GoodGuide and we are 100 per cent confident that Mr Squiggles, and all other Zhu Zhu toys are safe and compliant with all US and European standards for consumer health and safety in toys.
"We are contacting the GoodGuide people at the moment to share with them all of our Mr Squiggles and Zhu Zhu Pet testing data so we can get to the bottom of how their report was founded.
Hornsby went on to insist the toys are 100 per cent safe and in compliance with with all US and European toy safety standards.
He continued: "I have been in the toy industry for more than 35 years, and being a father of children myself, I would never allow any substandard of unsafe product to hit the shelves That's why we always test to not only meet but also exceed safety standards."
