The Food and Drug Administration (FDA) says its rules, along with federal laws, stop employees from improperly cashing in on their government service. But how adequate are those revolving door controls? Science has found that much like outside advisers, regular employees at the agency, headquartered in Silver Spring, Maryland, often reap later rewards—jobs or consulting work—from the makers of the drugs they previously regulated.

FDA staffers play a pivotal role in drug approvals, presenting evidence to the agency's advisory panels and influencing or making approval decisions. They are free to move to jobs in pharma, and many do; in a 2016 study in The BMJ, researchers examined the job histories of 55 FDA staff who had conducted drug reviews over a 9-year period in the hematologyoncology field. They found that 15 of the 26 employees who left the agency later worked or consulted for the biopharmaceutical industry.
