Thousands of sippy cups have been recalled due to a lead scare.

The products affected include Green Sprouts Stainless Steel Sippy Cups, Sip & Straw Cups and Stainless Steel Straw Bottles.

The Consumer Product Safety Commission says the base of the products can become detached,  exposing a piece inside that contains lead.

So far, there have been seven reports of the base breaking off, but no one has become sick.
