Subway is on the hook for its tuna once again after a lab report found there’s no actual tuna DNA in its sandwiches and wraps. The New York Times had 60 inches of Subway tuna sandwiches from three different restaurants in Los Angeles lab tested.
The chain was accused in a lawsuit reported earlier this year, alleging the fish is made from a mixture of various concoctions, first reported by the Washington Post. The tuna was frozen and sent out to the lab, which determined no amplifiable tuna DNA was present in the sample and so we obtained no amplification products from the DNA.
The lab determined two potential reasons why no tuna was detected in the sample, saying that 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. Experts said that when tuna is cooked, its protein breaks down, making it hard to identify, so the lab results may not be accurate.The food fraud investigation comes on the heels of a complaint filed with the U.S. District Court of the Northern District of California suing the sandwich chain for fraud, with the plaintiffs alleging they were lied to and tricked into buying food items that wholly lacked the ingredients they reasonably thought they were purchasing.
