An investigation of Georgia-based Angel Food Ministries by the IRS and the FBI is not denting demand for its services.

“We have seen increases over the years,” said Martha Kenemer, an Angel Food volunteer for six years at Trinity United Methodist Church in Dalton. “There are now more than ever due to the economy.”

Angel Food officals vow deliveries will continue, even though federal agents in February raided the office in Monroe, Ga.

Founders Joe and Linda Wingo are under criminal investigation and subject to a civil suit filed by two former board members regarding alleged financial improprieties.

They started Angel Food in 1994 to deliver quality food at low cost to 34 families. Today it’s a 40-state network that distributed nearly 6 million boxes of food in 2008.
