These are some of the new realities of food pantries around New York City, three months after a $5 billion national cut to the federal assistance program. For those who use the Supplemental Nutrition Assistance Program (SNAP), known as food stamps, it could get worse. Congress is currently considering cutting billions more as it considers the farm bill.
