Excerpt from the report: The difference between the returns the farmer receives for the quantity of wheat and other farm-produced ingredients used in baking a pound loaf of bread (including the domestic marketing certificate paid by the wheat miller), and the price the consumer pays for the loaf of bread is termed the "PRICE SPREAD," the "FARM-RETAIL SPREAD," or "MARKETING SPREAD." The marketing spread includes all charges for handling, storing, transporting, and processing wheat and other farm-produced ingredients; the cost of non-farm-produced ingredients to the baker; and baking, distributing, and retailing the bread sold by food stores.
