"From her research on infectious disease at the National Institutes of Health to her work on public health at the Department of Health and Human Services to her leadership on biodefense at the Nuclear Threat Initiative, Dr. Hamburg brings to this vital position not only a reputation of integrity but a record of achievement in making Americans safer and more secure," Obama said.
According to the White House, Hamburg was one of the youngest people ever elected to the National Academy of Sciences’ Institute of Medicine.
Hamburg's nomination now goes to the U.S. Senate for confirmation.
Obama also made three other key announcements:
–Baltimore Commissioner of Health, Dr. Joshua Sharfstein, has been selected to serve as the FDA's principal deputy commissioner.
- A new Food Safety Working Group will coordinate with other agencies and advise the president on improving coordination throughout the government, as well as examining and upgrading food safety laws.
- The Agriculture Department is set to close a loophole to prevent diseased cows from entering the food supply - along with implementing new measures to increase the number of food inspectors and modernize food safety labs.
"In the end, food safety is something I take seriously, not just as your President, but as a parent," Obama said. "When I heard peanut products were being contaminated earlier this year, I immediately thought of my 7-year old daughter, Sasha, who has peanut butter sandwiches for lunch probably three times a week. No parent should have to worry that their child is going to get sick from their lunch."
