PITTSBURGH (AP) _ H.J. Heinz Co. has acquired an Iowa company that manufactures frozen heat-and-serve soups served in hotels and restaurants.

Terms of the acquisition of Quality Chef Foods Inc., based in Cedar Rapids, Iowa, were not disclosed.

Heinz president William R. Johnson said the acquisition complements Heinz's existing Chef Francisco frozen soup line, which also serves hotels and restaurants.

He said frozen heat-and-serve soups are expanding at a rate of 10 percent to 12 percent annually and represent one of the fastest-growing segments of the American food service industry.

Quality Chef has annual sales of $30 million. The company operates an 80,000-square-foot factory in Cedar Rapids with nearby warehouse and distribution facilities.

Heinz's food service business has annual sales of $1 billion and manufactures Heinz ketchup, condiments, frozen soups and tomato products. The company overall has annual sales of more than $9 billion.
