Heinz Will Narrow Focus: The Pittsburgh-based company will retain and concentrate on six key businesses that generate 75% of its sales: food service, baby food, catsup and condiments, pet food, tuna, and its Weight Watchers foods and meetings units. H.J. Heinz Co. will sell businesses in the U.S. and abroad as part of a major restructuring plan to jettison flagging operations and reduce debt. The company would not say which units it will sell.
