In April 2017, Subway released a chicken welfare policy[82] that states that by 2024 or sooner, 100% of its U.S. chicken products will be produced in alignment with Global Animal Partnership (GAP) standards for higher welfare breeds, enhanced living environments (including lighting, litter, and enrichment), increased activity levels and optimized stocking density, and improved slaughter methods. To ensure compliance, Subway's chicken suppliers will be third-party audited with updates communicated annually.[83]
