Mondelez International switching to cage-free eggs

Deerfield-based Mondelez International says it will use exclusively cage-free eggs in the U.S. and Canada by 2020 and in Europe by 2025. The maker of Oreo cookies, Nabisco biscuits and Cadbury chocolates has already switched to 100 percent cage-free eggs in its European chocolate brands, as well as in other snacks sold in Belgium and the Netherlands.
