Chain Reaction IV: Burger Edition

This year’s Chain Reaction report and scorecard focuses on antibiotic use policies and practices for beef sold in the top 25 U.S. burger chains. Though not our primary focus, Chain Reaction authors also surveyed and reported on progress related to antibiotic use across all meat and poultry supply chains of the nation’s top 25 fast food and fast casual restaurants (some companies overlap between the two scorecards).
