Mars Incorporated, a global maker of food, snacking, and pet care products, has announced plans to open a new Royal Canin pet food manufacturing facility in Lewisburg, Ohio. The company, which produces brands such as CESAR, SHEBA, and M&M’S, has invested $450 million in the project and will create up to 270 new full-time jobs over the next five years.   

The 450,000-square-foot facility will manufacture Royal Canin’s complete dry kibble portfolio for the region, making it the brand’s largest dry pet food plant in the world. Once fully operational, the plant will produce enough dry pet food annually to feed 4 million cats and dogs. 

The site was designed with standardized systems and processes used at other Royal Canin locations to ensure consistent product quality. It has also earned Silver Leadership in Energy and Environmental Design (LEED) certification for its sustainability features.

The Royal Canin facility in Lewisburg provides an important opportunity to further Mars science-based innovation while supporting a community of people and pets that has long been a part of the Mars family.”
