I realize you're being sarcastic, but food inspections are continuing. From http://www.agweek.com/event/article/id/21778/

  If the U.S. Department of Agriculture shuts down at midnight tonight,
  food stamp benefits will be delivered for the month of October, forest 
  fires will continue to be fought, meat and poultry will still be inspected,
  grain inspection will continue, laboratory animals will be fed and the
  rural development division will still monitor government loans.

  But USDA will not release any new production statistics, most of the
  rest of USDA will shut down and its website may go dark.
