We know there’s been a lot of talk on this topic, including misinformation generated in the media, so we created this page to set forth the facts and help clarify any misunderstandings.

Tuna Fact Check

MYTH The New York Times reported Subway’s premium, fan-favorite tuna wasn’t actually tuna.

TRUTH Not true! What actually happened is that the New York Times commissioned a test that couldn’t detect tuna DNA in their sample. According to scientific experts, this is not unusual when testing cooked tuna and it absolutely doesn’t mean the sample that was tested contained zero tuna.


The New York Times test results only show that the type of DNA test done by the unnamed lab wasn’t a reliable way of determining whether the sample was tuna or not. If the test had confirmed the existence of a protein other than tuna, questions could have been raised. However, their “non-detect” conclusion really just means that the test was inadequate in determining what the protein was. In other words, it was a problem with the test, not the tuna.


Still not convinced? Check out USA Today’s independent fact check of the New York Times’ conclusion, which found it lacked important context about the limitations of DNA testing of denatured proteins, and some additional information from food DNA testing firm Applied Food Technologies about why DNA testing isn’t always conclusive in testing processed tuna given the cooking and packaging process breaks down the DNA fragments. The challenge of accurately testing processed tuna DNA has been known for a while, and even studied by scientists.


Additionally, the reckless complaint that spurred this misinformation was rightfully dismissed by the Court on October 7, 2021. While the plaintiffs have filed an amended complaint, Subway is moving swiftly to file a new motion to dismiss the lawsuit once again.

Tuna Q&A

Has anyone else ever tested Subway’s tuna?

Yes. We test our tuna regularly to ensure it meets Subway’s stringent quality and safety requirements. And, of course, we have to comply with FDA regulations. But you don’t have to take our word for it. Applied Food Technologies is one of the only labs in the country with the ability to test broken-down fish DNA, which makes it more accurate in testing processed tuna. AFT conducted more than 50 individual tests on 150 pounds of Subway’s tuna for Inside Edition and confirmed yellowfin and/or skipjack tuna in every sample.

What requirements are in place to ensure that the tuna I buy is real tuna?

The processing and selling of tuna is highly regulated by governments around the world. In the U.S., the FDA has strict rules that we have to follow. In addition, the Seafood Import Monitoring Program (SIMP) requires complete traceability of all tuna from time of catch through processing into finished goods and is required by U.S. Federal law.

What other quality control mechanisms are in place to ensure I’m getting 100% tuna?

In addition to standard testing and food quality measures taken to ensure the premium quality of all the food Subway serves, there are several certificates associated with the tuna in Subway’s U.S restaurants.


• The Fisheries Certificate of Origin—a form provided by NOAA Fisheries—lists the exporter and importer information for the tuna, the exact species of the tuna, and the catch method.


• The Captain’s Statement includes the boat captain’s name and verification of the catch method and traceability information, including the Food and Agriculture Organization’s major fishing area identification number.


• And the Catch Certificate lists the name of the boat that caught the fish and each volume of species harvested on that ship in metric tons. Subway’s tuna is also certified Dolphin Safe and Kosher.

What is the status of the lawsuit that started all of this misinformation?

• The Court dismissed the reckless and improper complaint surrounding Subway’s tuna on October 7, 2021. While the plaintiffs have filed an amended complaint, Subway is moving swiftly to file a new motion to dismiss it, as our position has not changed – we serve 100% real, wild-caught tuna.

What about the allegations that Subway tuna is processed beyond recognition, is “flake” tuna or may contain other kinds of fish protein?

FDA-regulated Subway importers use only 100% wild-caught tuna from whole round, twice cleaned, skipjack tuna loins. Reclaimed meat and flake are strictly prohibited by our standards. The tuna that Subway guests enjoy is not processed any differently than canned or pouch tuna found in the average supermarket.


It’s also important to note that the word “flake” can be used in two different contexts when it comes to tuna, and this misunderstanding is a matter of semantics. Flaked tuna is not the same as tuna flake. Subway’s tuna product is listed as “Flaked Tuna in Brine” on its labels to describe the preparation of the tuna—specifically the piece size and the texture. It may display differently on the import records, where it appears to be written in short-hand. Subway specifically prohibits the use of any tuna flake, byproduct, or remnants in its tuna.

Who sources Subway tuna?

In the U.S., Subway’s tuna importers are Rema Foods and Jana Brands.


Rema Foods is a family-owned business, founded in 1964. It is a leading global food supplier, focused on providing unique specialty and commodity-based products. Their company has been a proud food supplier to Subway Restaurants for more than 20 years.


Steve Forman established Jana Brands in 1970. He grew it from a one-man business in a one-room office to a multi-national, multi-million-dollar seafood company. Jana Brands prides itself on being an innovative company since its inception bringing the industry high quality frozen and shelf-stable seafood products.
