WASHINGTON -- Four importers are recalling 150 million pieces of toy jewelry sold in vending machines across the United States.

The Consumer Product Safety Commission says some of the pieces have dangerous levels of lead and pose a poisoning risk to children.

The commission says about half of the 150 million pieces contain lead, but the industry decided to recall all of it, since it's difficult to distinguish lead from non-lead jewelry.

No reports of injury or illness have been received for the recalled products announced Thursday.

The toy jewelry was sold in vending machines nationwide from January 2002 through June 2004.

The items cost between 25 cents and 75 cents.

The recall involves various styles of rings, necklaces and bracelets.

The rings are gold- or silver-colored with different designs and paint finishes with various shaped center stones.

The necklaces have black cord or rope or gold- or silver-colored chains and have pendants, crosses or various other designs.

The various styles of bracelets include charm bracelets, bracelets with medallion links, and bracelets with faux stones.

The commission says parents should throw away recalled jewelry.
