There is actually a lawsuit on this….
A New York Times analysis found no identifiable tuna DNA in Subway’s tuna sandwich, the newspaper reported over the weekend, citing tests conducted by a commercial lab.
The Times bought 60 inches of Subway tuna sandwiches from three different Subway locations in Los Angeles.
A reporter for the newspaper then removed and froze the tuna and sent it to an unidentified commercial food testing lab. The newspaper said it paid roughly $500 for the lab to conduct a PCR test to see if the substance had one of five different tuna species.
After a month, the lab said it found “no amplifiable tuna DNA was present in the sample and so we obtained no amplification products from the DNA.”
“Therefore, we cannot identify the species,” the lab said.
Elaborating on the results, a spokesperson for the lab told the Times that there were two different conclusions.
“One, it’s so heavily processed that whatever we could pull out, we couldn’t make an identification,” the spokesperson said. “Or we got some and there’s just nothing there that’s tuna.”…
The test comes as Subway faces a class-action lawsuit alleging that its tuna sandwich is not actually made of tuna. The suit was first filed in a California federal court in January.
In an amended complaint dated June 7, the plaintiffs allege that Subway claims to sell sustainably caught skipjack and yellowfin tuna but was instead selling “anything less than healthy stocks.”….
