The tuna sandwich from the high-speed restaurant chain Subway continues to pose a puzzle.

After a class action lawsuit against the company in a California court, according to which no tuna was to be found in the tuna spread, the New York Times bought several of the sandwiches in various subway branches in Los Angeles and sent them to a food laboratory.

There the newspaper had the spread sold as "Tuna" examined.

“No tuna DNA was found in the sample.

Therefore, the species cannot be determined, ”the newspaper quoted the results of the investigation.

The laboratory offered two explanations: either the spread had been treated so severely that it could no longer be detected, or it simply did not contain any tuna.

Subway referred to the allegedly unsafe test method.

“DNA testing is simply not a reliable way to detect denatured proteins like the company's tuna.

The tuna was cooked before it was tested. "

The "Tuna Drama"

Subway, founded more than 55 years ago in the state of Connecticut and today the fastest growing franchise company in the world, is considered scandal-proven. In 2015, the group's former advertising face, student Jared Fogle, was sentenced to 15 years in prison on charges of child pornography and sexual abuse of minors. Last year, the Supreme Court in Ireland ruled that the high sugar content made the famous footlongs and other breads sweet.

The mystery of the tuna sandwich, which is very popular with customers, remains unsolved for the time being. The investigative magazine of the broadcaster CBS, Inside Edition, had already taken the trouble a few months ago to have a few samples of the "tuna" mixed with mayonnaise according to Subway examined. The reporters bought from stores in New York and sent the samples to a laboratory in Florida for DNA testing. The result? "We can confirm that all three samples contain tuna," announced LeeAnn Applewhite, head of Applied Food Technologies.

The "Tuna drama" now awaiting legal clarification in California is amusing thousands on social media. "Half of my text messages are about the mayoral election in New York," tweeted one user. "In the other half, my friends try to find out what the hell they had in their mouths when they ordered tuna from Subway."
