Do changes in antibiotic use in animals lead to changes in resistance in people? It's a bit of yes, no, maybe situation because it's complicated. However, there are some good data showing that what we do in animals can affect resistance in humans.  We dug into the archives for this interesting and still highly relevant 2010 paper (see link below) about changes in the use of ceftiofur in chickens and 3rd generation cephalosporin resistance in Salmonella from people.https://pmc.ncbi.nlm.nih.gov/articles/PMC2874360/
