General Mills plans to close two plants employing 680 people as part of an effort to cut corporate costs by another $100 million.
The news comes a day after the Golden Valley-based food company reported disappointing sales and a 25 percent drop in its quarterly net income.
One plant in Lodi, California, primarily manufactures cereal. Production would be shifted to other General Mills facilities. The other plant in Methuen, Massachusetts, makes yogurt. The company said it is optimizing its yogurt manufacturing network, consolidating production at other facilities.
General Mills said it will provide severance and transition benefits to affected employees.
