Chipotle is the lone A-student. Chipotle's cattle suppliers are prohibited from using antibiotics, so the chain's reported use of antibiotics in beef is nil.
Of course, Panera is right behind them with an A-. The business first offered chicken that had been produced without antibiotics in 2004.
Shake Shack received an A in PIRG's 2018 assessment, and the current study praises the restaurant for leading the antibiotic-free beef movement.
BurgerFi's commitment to serving only beef raised without the use of antibiotics has earned them praise from customers year after year.
B.Good, a Boston-based chain having locations in various states, is also recognized by PIRG's Chain Reaction scorecard.
Burgerville, an Oregon and southwest Washington restaurant franchise, claims that its antibiotic-free meat is sourced from cattle grown in the Pacific Northwest.
Grass Run Farms provides all Burger Lounge locations in California with antibiotic- and hormone-free beef of the highest grade.
Elevation Burger in Virginia also garnered a mention on the Chain Reaction scoreboard. Its 40-plus national and international sites serve grass-fed, organic beef.
