The "Check-Ups" are lacking in many school cafeterias.
Millions of American school children are eating in cafeterias that are not inspected twice a year, as Congress requires.
The Associated Press found 10% of schools were not inspected last year, and 30% only got one inspection.
The Agriculture Department runs the inspections and looks for violations.
That includes foods stored at the wrong temperatures and workers who do not wash their hands.
The inspection rules apply to schools where the Federal Government provides free or reduced lunches to low income children.
