Bay Valley Foods, a division of TreeHouse Foods, is to close its Portland, Oregon pickle plant due to a drop in volumes.

The closure, expected to take place in early June, is likely to affect 88 employees.

George Jurkovich, senior vice president of operations, said: "We have experienced a reduction in our pickle volumes and Portland is our highest cost and lowest-utilised facility. Thus, we find it necessary to consolidate our manufacturing network and close the Portland plant."

Current production at Portland is expected to be absorbed by other Bay Valley Foods facilities.

In May last year, TreeHouse bought leading processor and distributor of pickles DeGraffenreid, from Bell-Carter Foods for US$10m.

The Missouri-based company was integrated into the Bay Valley Foods division.
