More than 52,000 units of M&M's-branded jewelry is being recalled because the pieces contain high levels of lead.

The recall involves all M&M's-branded jewelry, including some children's jewelry, sold at M&M's World stores between May 2015 and June 2016.

The items include earrings, rings, bracelets and necklaces.

Lead is toxic if ingested by young children and can cause adverse health issues.

Consumers should immediately stop using the recalled jewelry, place the items out of the reach of children, and contact M&M's World or visit an M&M's World Store to return the jewelry for a full refund.

M&M's World can be reached at 866-915-5058 from 9 a.m. to 5 p.m. ET Monday through Friday or online at and click on the "Product Safety & Recalls" link at the bottom of the page for more information.
