Developed by United Egg Producers and voluntarily implemented by egg farmers in 2002, this program outlines science-based guidelines for the care and well-being of hens. Any egg farm wanting to market eggs as UEP Certified must implement the scientific guidelines on 100 percent of their flocks. An independent, third-party audit program assures that each farm complies with the guidelines. The UEP Certified logo signifies eggs originate from farms dedicated to responsible, science-based practices to ensure optimal hen care.
