What's Going On With Subway's Tuna Sandwiches?
(Newser)  We already know that Subways bread isnt breadits cake. Now DNA testing cant confirm the tuna is tuna. Well, actually, probably not. Its true that two people in California started a class-action lawsuit accusing Subway of putting something else in the tuna sandwicheswithout specifying what that something might be. A New York Times reporter decided to try to plumb the depths of this seafood issue by buying up five feet of sandwiches, just the tuna and no veggies, and shipping them off to a lab for testing. The results seemed fishy, initially. No amplifiable tuna DNA was present in the sample and so we obtained no amplification products from the DNA, the lab said. Not necessarily! All canned tuna is cooked. Subway tuna is further processed by blending it with mayonnaise. Thats a lot of processing, and just the cooking is enough to denature proteins and make DNA results hard to pin down. The lab clarified that while its possible theres DNA that isnt tuna, its totally possible that there was no usable DNA to amplify. Inside Edition had a test done back in February, and their lab found DNAtuna DNA. And the lawsuits plaintiffs have more or less conceded, too, asking Subway only to prove that 100% sustainably caught skipjack and yellowfin tuna. If youre confused, youre not alone. Jessica Simpson, who is still apparently living down the time she wasnt sure if Chicken of the Sea was tuna or chicken, tweeted her support: Its OK @SUBWAY. It IS confusing.
