The 17,000-square-foot addition to the existing site will house all of its processing equipment, according to Dairyfood USA president Dan Culligan.

Dairyfood USA’s extended-shelf-life, or processed, cheeses include specialty spreads, bars, wedges and naturally smoked cheeses for gift-pack, airline, food service, snack and retail companies. Most of those companies put their own labels on the products.

Culligan said food safety and an opportunity to expand product lines were the biggest reasons for the expansion.

Significant production increases of its spreads and smoked cheeses has helped Dairyfood USA increase revenues by about 18 percent for fiscal 2013, Culligan said.
