The groups collected 559,885 pounds of food March 5. That was enough for Guinness to certify a new record Wednesday.
"The event could not have happened with the support of a large number of people," said Brent Kappler, president of the Veterans Corps, in a news release. "I am proud of the work of our members and for their commitment throughout the day and night driving forklifts, weighing food, and loading and unloading pallets."
The Durham total beat both the previous official Guinness record of more than 509,000 pounds and a pending record of more than 515,000 pounds.
The school invited the Veterans Corps to help break the record because of their logistical operations experience with events such as Operation Coming Home and Extreme Makeover.
"It was very apparent what the USVC meant to the students and staff of the North Carolina School of Science and Math in achieving this world record," Kappler said. "Congratulations to the students and staff of the N.C. School of Science and Math."
Guinness World Records will present the new record holders with a certificate to commemorate their achievement. The school and others involved also will celebrate the achievement April 13.
