USA TODAY The website, subwaytunafacts.com, established a tuna fact check where it stated that a recent New York Times investigation claiming that its tuna isn't real is a myth. "What actually happened is that the New York Times commissioned a test that couldn’t detect tuna DNA in their sample. According to scientific experts, this is not unusual when testing cooked tuna and it absolutely doesn’t mean the sample that was tested contained zero tuna," the website states. It also cites a USA TODAY Fact Check, which rated that the investigation was missing context because different tests have detected tuna in Subway sandwiches and experts said canned tuna becomes denatured when cooked.
