The feds have a problem with what they term inefficiency in the distribution of food stamps to the needy by the state of Georgia. But state Department of Human services officials point out that a backlog of more than 26,000 past-due food-stamp renewals has been whittled down to less than 2,000 in about a month. Nothing less than a seven-day-a-week effort has gotten the situation under control.  This is a ship that has been salvaged and is now close to SAILING again.
