Agriculture Department Inspector General Phyllis Fong suggested threatening to prevent contractors from doing business with the government either temporarily (suspension) or over the long-term (debarment) to deter rebate schemes, in which companies that receive rebates from food manufacturers for large-volume purchasing leave them off invoices and pocket the difference. The IG has been investigating contractors providing food purchasing services for the National School Lunch Program since 2002, and has found omitting information on rebates to be a frequent issue.
Withheld rebates account for between 5 percent and 50 percent of the price charged to the school districts participating in the lunch program, John Carroll, assistant attorney general for New York, told the Senate Homeland Security and Governmental Affairs Subcommittee on Contracting Oversight.
"Every dollar that's being lost through rebate schemes is a dollar we cannot use to feed our soldiers and our children who need nutrition," said Sen. Claire McCaskill, D-Mo., chairwoman of the subcommittee.
Previous USDA audits found a service management company overcharged school districts more than $8 million through inflated invoices in 2003, and another company received $1.3 million in hidden rebates in 2005.
Agriculture's inspector general is starting a new investigation this month to assess the effectiveness of the recommendations issued after previous audits.
Similar fraud occurs with contractors working with the Defense Department to provide food to soldiers serving overseas, witnesses said.
Public Warehousing Co. is reportedly in talks to reach a settlement with the Justice Department after allegedly violating its prime vendor contract with the Defense Logistics Agency, overcharging the agency for food costs by $8.5 billion in 2009.
Charles Tiefer, a former member of the Wartime Contracting in Iraq and Afghanistan Commission and a law professor at the University of Baltimore, suggested revising contracts to allow auditors more access and requiring companies to identify any rebates on invoices. Tiefer also recommended conducting a survey of contractors to determine the extent of rebate schemes.
McCaskill announced that the subcommittee intends to submit document requests to investigate the issue more. "I think there's real money here if we pull this thread," she said.
CORRECTION: An earlier version of this story misstated the status of the contractor Public Warehousing Co.'s case involving allegations of overcharging the Defense Logistics Agency for food costs in 2009. The case remains unsettled, and the company, since renamed Agility, says it did nothing wrong.
