A list of potentially hazardous toys was released today, just in time for the holiday shopping season.

Public Interest Research Group, a national nonprofit organization, said it wants parents to be aware that many children’s toys still contain high levels of lead, cadmium, arsenic and other harmful chemicals.

Serena Unrein, public interest advocate for PIRG Arizona, said that even though most children’s toys are manufactured overseas, companies need to adhere to U.S. safety standards.

“About 80 percent of all toys that end up on shelves in the country are manufactured outside the U.S," she said. "Ultimately, these companies that are selling their products in the U.S. need to be sure that their products are safe for American consumers.”

Parents should be aware that even brand name toy manufactures sometimes violate U.S. consumer and pediatrician standards, she added.

This can happen when toys meant for infants and toddlers include small parts that could be a choking hazard, such as a Fisher-Price toy barbecue set manufactured by Mattel.

Unrein cautioned parents and other consumers, who are buying toys for the holidays, to carefully read product labels before purchase.

She said a list of toys deemed dangerous can be found online at PIRG’s website.
