Ralston to Close a Pet Food Plant

Ralston-Purina Co. said it will close its pet food plant in Mechanicsburg, Pa., in late November or early December, continuing a streamlining effort.

The facility, one of eight Ralston pet food plants in the United States, opened in 1970 and makes a complete line of dry foods for dogs and cats. Production will be shifted to other plants, the company said.

The date of the closing will depend on production schedules, a company spokesman said.
