Consumers perceive organic meat as a more healthful food because the birds are not raised with antibiotics, and this is a primary reason why consumers purchase organic poultry products, driving sales of organic poultry meat and eggs, which increased 151% over a 1-year period (1999 to 2000) and which have continued to increase since 2000.
