A GAO investigation found that the Agriculture Department didn't always make sure states and schools were notified promptly about suspect food distributed through the federal school lunch and breakfast programs, which serve 30 million students.
GAO reported Tuesday that it took several days to a week for states to figure out which products were recalled, and that schools may have served the suspect food to kids during that time.

Congressional Democrats asked for the investigation. Democratic Sen. Dick Durbin of Illinois said it shows the need for comprehensive food safety reforms.
Agriculture Secretary Tom Vilsack said safety is of utmost importance and his department is working on new recall policies.
