The commercial poultry industry is getting safer, thanks to the work of Hyun Lillehoj. She's senior research molecular biologist at the Agricultural Research Service and has been with USDA for more than 30 years. Her research has helped prevent and treat diseases in commercial poultry without the use of traditional antibiotic drugs. She's a finalist for a Service to America Medal in the career achievement category for making the world's poultry supply safer for all of us and making U.S. producers more competitive around the world. She tells In Depth guest host Jared Serbu about her work which has been described as a "game-changer" for the poultry industry. View a photo gallery of Sammies finalists.
