When people get some sort of foodborne illness, you want the source off the market as soon as possible. At one time that took weeks or even months.

For his work, he’s a finalist in this year’s Service to America Medals program. Federal Drive host Tom Temin talked with Dr. Steven Musser, deputy director for scientific operations in the F-D-A’s center for food safety and applied nutrition.
