The halal status of Subway’s tuna varies by location. Subway tuna in the United States is not guaranteed to be halal due to cross-contamination risks and the general sourcing practices of Subway. In the UK and Ireland, a limited number of Subway locations offer a halal menu, clearly identified by signs on the door. In Turkey, all Subway menu items, including tuna, are halal certified. It’s essential to verify the halal status directly at the specific Subway location.

And Allah knows best.
