The competition, which kicked off Monday and runs through Nov. 21, pits the two offices against each other for who can donate the most food to the Second Harvest Food Bank in Nashville.
Dean won the competition last year. He is challenging Metro departments to raise 125,000 pounds of food, the same amount raised in 2012, which was the most successful year of the Metro food drive.
Last year's drive brought in 122,000 pounds, enough to provide about 101,000 meals.
According to Second Harvest, more than 1 million Tennesseans find themselves in dire need of food.
