                                Subway's tuna has been the subject of multiple lawsuits and controversy over the years, stemming from allegations that it wasn't real tuna. Despite this, Subway has consistently maintained that its product contains 100% wild-caught, real tuna. The discrepancy arises primarily from the challenge of DNA testing highly processed and cooked fish.
