No ’wich craft in our tuna, CEO says

The head of Subway insists there’s nothing fishy about his company’s tuna.

CEO John Chidsey vehemently denied allegations that the tuna in the fast-food giant’s sandwiches is fake — as he declared that the Subway’s fish is no mystery meat of the sea.

“[It’s] 100-percent tuna,” John Chidsey said Tuesday on Fox Business. “We 100 percent stand behind our tuna.”

Chidsey’s backing comes on the heels of an investigation last month by The New York Times, which sent frozen Subway tuna samples to a testing lab that said it couldn’t find any tuna DNA.

The newspaper said the lab did a polymerase chain reaction, or PCR, test to see if the substance in the sandwiches had any of five different tuna species.

More than a month after the samples were submitted, the lab results read, “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.

A spokesman for the lab offered two possible conclusions from the results.

“One, it’s so heavily processed that whatever we could pull out, we couldn’t make an identification. Or we got some and there’s just nothing there that’s tuna,” he told the Times.

Subway pushed back on the results immediately, with spokeswoman Lorri Christou dismissing the report as “baseless” and saying that “DNA testing is an unreliable methodology for identifying processed tuna.”

Chidsey echoed that point in his remarks Tuesday.

“If you follow the science, once tuna is cooked, its DNA becomes denatured, which means you can’t tell once the product’s been cooked,” he said.
