If you ate a hamburger today, or a high-priced steak, chances are it came from an animal that was fed an antibiotic during the last few months of its life.
This is one of the most controversial uses of antibiotics in the entire food industry. There's growing pressure on the beef industry to stop doing this.
I wanted to know how hard that would be. My questions eventually led me to Phelps County Feeders, a cattle feedlot near Kearney, Neb.
