Subway requires all suppliers that supply into the Subway system to comply with our Vendor Code of Conduct. Subway’s Vendor Code of Conduct prohibits forced labor/slavery as well as establishing our expectations for employment, workplace practices, compensation and benefits, discrimination, health and safety. We are continuously working towards making the safeguards of our supply chain more robust and ensuring compliance with our standards.

We recognize the vital importance of sustainable fishing—both commercially and ecologically. Subway sources wild-caught skipjack tuna, certified by the Fisheries Certificate of Origin and a Captain’s Statement to verify traceability. We strive to work with the industry to move to more sustainable practices including sourcing our seafood from independently certified sustainable fisheries, supporting protected areas and maintaining healthy and sustainable fish stocks.

As of November 1, 2025, ahead of our commitment deadline, all Subway restaurants in the U.S. and Canada source 100 percent cage-free eggs. This multi-year transition fulfills our promise to source 100 percent cage-free eggs for the more than 22,000 restaurants across North America.

In Europe, the Middle East, Australia, and New Zealand, 100 percent of the eggs we purchase are either free-range or cage-free. In other regions where supply is limited, we are committed to working with the industry and suppliers to find solutions to source cage-free or free-range eggs.

In the U.S. and in line with World Health Organization guidance, our sandwiches, wraps, and salads are served only with chicken raised without antibiotics important to human health.

In collaboration with our suppliers, Subway is progressing on the implementation of physical standards to improve broiler chicken welfare. Most notably, we prohibit the use of broiler cages in 100% of our poultry supply in the U.S. and are prioritizing the condition of friable litter and access to functional enrichments for all birds.

We continue to monitor the ongoing research and development of broiler chicken welfare standards considering the industry’s capacity to meet our demand for product. Aligned with evolving stakeholder expectations, we are working to further define our roadmap for improving broiler chicken welfare.

Subway® recognizes the importance of sow and piglet welfare in our pork supply chain, and supports sow husbandry and housing approaches that create improved animal welfare outcomes. In accordance with local regulations, we have completely phased out gestation crates in our European supply chain. In other regions, we are engaging with suppliers and industry groups to monitor and align with evolving best practices for sow housing while maintaining commercially viable pricing.
