Wal-Mart is pulling Miley Cyrus-brand jewelry from its shelves after tests performed for The Associated Press found the jewelry contained high levels of the toxic metal cadmium.

Wal-Mart said in a statement released three hours after AP’s initial report of its findings Monday the store would “remove all of the jewelry from sale” while it investigates.

The items are not know to be dangerous if they are worn. Concerns come when youngsters bite or suck on the jewelry, as many children are apt to do.

Long-term exposure to cadmium can lead to bone softening and kidney failure. It is also a known carcinogen, and research suggests that it can, like lead, hinder brain development in the very young.
