More than 300,000 Kentucky households are now receiving food stamp assistance. Between June 2008 and June of this year, more than 38,000 new families signed up. Kentucky Department for Community Based Services spokesman Mark Cornett says that’s the single largest increase in the program’s history here.“It’s mostly working families, who either one or both parents were employed, and one or both parents have lost their jobs and they’ve never walked into our offices before," Cornett said.Cornett says caseworkers are working over time to process applications. He says a recent influx of nearly three million in federal stimulus dollars will help the department streamline and modernize its operations.
