North Carolina may have new troubles meeting a deadline from federal regulators demanding that backlogged food stamp applications be cleared. Health and Human Services Secretary Dr. Aldona Wos told a General Assembly oversight committee Wednesday social service offices had appeared on track to resolve the roughly 500 applications by next Monday. But now she’s worried news of additional pending applications in Guilford County could put a damper that goal. Wos says the Guilford applications hadn’t been entered into the state’s computer system for determining eligibility for government services. She didn’t immediately have a number on the additional household applications. The state met a deadline last month from the U.S. Agriculture Department to handle most pending applications or potentially lose funds to administer the program. Now USDA wants the remaining applications resolved.
