HJ Heinz has been ranked as the highest food company on the University of Michigan's American customer satisfaction index, the US-based food giant said today (18 November).

This is the ninth year that Heinz has been the index's top-rated food company, the group said.

"We are proud that Heinz continues to earn the trust of consumers with foods that provide the best consumer satisfaction in terms of good value and which consistently exceed expectations for millions of American families every day," said William Johnson, Heinz chairman, president and CEO.

"Consumers love the Heinz brand and we plan to continue providing consumers with new reasons to try our foods as we innovate in terms of taste, nutrition, affordability and convenience."

The index is produced by the University of Michigan's Ross School of Business in partnership with the American Society for Quality and CFI Group.
