Happy Pi Day! Obama focuses on food and drug safety this week.

There are certain things only a government can do. And one of those things is ensuring that the foods we eat, and the medicines we take, are safe and don’t cause us harm. That is the mission of our Food and Drug Administration and it is a mission shared by our Department of Agriculture, and a variety of other agencies and offices at just about every level of government.

The men and women who inspect our foods and test the safety of our medicines are chemists and physicians, veterinarians and pharmacists. It is because of the work they do each and every day that the United States is one of the safest places in the world to buy groceries at a supermarket or pills at a drugstore.
