The annual Spectrum Brands Corporate Food Drive Challenge has hit the halfway point. The proceeds of the friendly competition, which ends Nov. 30, will benefit the Northwest Arkansas Food Bank.

In addition to Spectrum Brands, other participants in this year’ challenge are Cargill, Castrol Oil, Englander, Signature Bank of Arkansas, Johnson Controls, Smuckers, General Mills, Kraft Heinz, Shell Oil, Newell Brands, PepsiCo, Simmons Bank, Unilever, ITW, Johnson & Johnson and Mondelez International.

Employees from each participating company will collect non-perishable food items and the donated food will be weighed on Nov. 30. The office with the most weight per capita will win a trophy to display at its offices.

All participating companies are invited to a celebration on Dec. 7, hosted by Spectrum Brands to celebrate the final results and announce the winner.

Items in the competition must be donated by employees and any donations purchased by the participating companies will not be included in the final weight. Cash donations will be included at a rate of three pounds for every dollar given.

Johnson Controls won the competition last year. More than 17,000 pounds of food was donated a year ago from 307 employees.
