Don't buy jewelry from vending machines. Despite recent recalls, there may still be some lead-based items out there.
Avoid fake pearls, which are often coated with lead paint, and jelly bracelets, which are sometimes made with vinyl that contains lead.
Call the manufacturer if you're unsure about a product, or test it with an inexpensive LeadCheck Swab kit, available at hardware stores.
Toss metal jewelry that you can't be sure is lead-free.
Call your doctor if you think your child has sucked on or swallowed something that contains lead.
