Carlos M. Gutierrez, chairman and CEO of Kellogg, said yesterday [Monday] that the Battle Creek-based company will begin growing again in 2002. With 2001 sales of US$8.85bn, Kellogg ranks as the largest cereal producer in the world, but two major changes last year affected growth and profit in the short term; a complete revamp of its operating strategy and the acquisition of cookie and cracker maker Keebler Foods.
