In-N-Out Burger beefs up its promise of antibiotic-free meat

The burger chain is joining a small group of fast food restaurants committing to using antibiotic-free meat

In-N-Out Burger has long set itself apart with its refusal to use frozen meat, microwaves and heating lamps, and a focus on higher-quality, freshly made food. But it hasn’t stood out in addressing a big public health concern about the tie between drugs used routinely to raise livestock and the increasing number of antibiotic-resistant infections in humans.

That’s changing. The burger purveyor recently announced it will join the small but growing number of fast food chains working to shift away from meat raised with antibiotics developed for humans.
