There are 15 species of fish that can be considered tuna, but Subway states they sell skipjack and yellowfin tuna, which a lab would know as Katsuwonus pelamis and T. Subway is the fast food chain with the largest number of restaurants both in the United States and worldwide 'DNA testing is simply not a reliable way to identify denatured proteins, like Subway’s tuna, which was cooked before it was tested.'

'This report supports and reflects the position that Subway has taken in relation to a meritless lawsuit filed in California and with respect to DNA testing as a means to identify cooked proteins. The unnamed lab conducted a $500 PCR test to determine if the Subway tuna was one of five different species, but found 'no amplification products from the DNA' and so they 'cannot identify the species.'Įarlier this year, a separate class-action lawsuit was filed against the fast food franchise alleging misrepresentation of the fish in their sandwiches after a similar DNA test.īut the chain said in a statement to FOX Business on Thursday: 'A recent New York Times report indicates that DNA testing is an unreliable methodology for identifying processed tuna. The fast food chain hit out the day after New York Times revealed it had sent more than 60 inches worth of tuna sandwiches to a lab after ordering them from the fast food franchise at various Los Angeles locations.
