Overall foodborne illness outbreaks have declined in recent years. But ones that stem from imported foods have risen sharply—from an average of three per year in the late 1990s to 18 annually between 2009 and 2015. That's the conclusion of a new study from the Food and Drug Administration and the Centers for Disease Control. A new rule, finalized under President Barack Obama, charges the FDA to ramp up oversight of imports, requiring that importers verify that their suppliers are meeting the same safety standards required of domestic producers, the study notes.
