June 23, 2021 — After facing a class-action lawsuit claiming that Subway’s tuna sandwiches do not contain tuna and the restaurant chain cannot prove the fish is sustainable, a new DNA lab report shows there is no tuna in the company’s tuna sandwiches.
The New York Times set up an independent lab test of 60 inches of tuna sandwiches from three Subway restaurants in Los Angeles, California. The testing, which included a polymerase chain reaction test that searched for DNA of five different tuna species, detected no tuna in the sandwiches.
