SALEM — NORPAC Foods has sold its canning business to Seneca Foods Corp.

“In our 93 years as a farmer-owned cooperative, our canning business has been an important part of our history, but over time, it gradually represented a smaller percentage of our overall business,” Shawn Campbell, president and CEO of NORPAC, said in a press release. He has been the company’s top executive since April.

The canning business represented 6 percent of the company’s volume, according to NORPAC spokeswoman Amy Wood.

“The company is now looking at really focusing energy on growth and innovation in the frozen category,” she said.

A spokesman for Seneca Foods declined to comment on the purchase.

NORPAC is a cooperative owned by more than 200 family farmers in the Willamette Valley, and provides frozen vegetables, fruit, soups and other value-added products to the foodservice, retail, club store, remanufacture and export market segments, according to its website.

The June 30 sale will result in the closure of a small Salem beet processing facility and the consolidation of the Hermiston, Ore., facility with the Brooks, Ore., and Quincy, Wash., operations. In 2018 the plants in Brooks and Stayton, Ore., will be redesigned to accommodate more frozen vegetable processing.

NORPAC will continue manufacturing other products for Seneca through late 2017.

“The transition away from our canning business and the closure of our Hermiston processing facility will help us drive efficiencies and reduce operational complexities as we invest in continued growth and innovation in our frozen product lines,” Campbell said.

In April, Seneca also acquired the remaining 50 percent ownership of Truitt Bros. Inc. from David Truitt, making the Salem-based company a wholly owned subsidiary. Truitt Bros. also has an operation in East Bernstadt, Ky.

Seneca Foods is the leading provider of packaged fruits and vegetables in North America.
