Tuna ‘100%’ found in new Subway tuna DNA testing: report – New York Daily News

“Inside Edition” tested the much-discussed tuna used in Subway sandwiches, salads and wraps and found, for the second time in five months, that the fast food chain does in fact use real tuna in its offerings.

This follows a June 19 New York Times report that it had purchased more than 5-feet of Subway tuna sandwiches to be tested at an undisclosed lab in California that failed to find “amplifiable tuna DNA” in the samples it examined, citing a couple possible reasons — either it’s so heavily processed no tuna could be detected or “there’s just nothing there that’s tuna.”

Subway didn’t initially comment on that testing, but has since pushed back arguing that by the time tuna reaches Subway customers, it’s been so heavily processed and “denatured” that its DNA wouldn’t be recognizable.

This follows a New York Times report that didn’t detect DNA, which Subway said is to be expected when fish is ‘denatured’
