NY Times test finds no identifiable tuna DNA in Subway’s tuna sandwich

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.”
