Scientific Advisory Committee

Nearly 20 years ago, in 1999, UEP convened an independent, unpaid Scientific Advisory Committee to evaluate egg-laying hen well-being standards, review existing research, conduct new research and recommend changes for egg farms. The first recommendations from this advisory committee became the foundation for UEP Certified. The advisory committee continues today, for ongoing review of new research and modern egg farm standards.
