Pescatarians may want to avoid eating Subway’s tuna, if one is to believe the allegations in a revived lawsuit questioning the ingredients in the restaurant chain’s seafood.

Nineteen of 20 tuna samples from Subway outlets throughout Southern California contained animal protein including chicken, pork or cattle, but no discernible tuna DNA, according to the latest complaint filed on Monday in U.S. District Court in California…

The complaint filed on Monday includes findings based on DNA tests by the Barber Lab at UCLA’s Department of Ecology and Evolutionary Biology. Beyond finding “no detectable tuna DNA sequences whatsoever” in 19 of the samples, all 20 held “detectable sequences of chicken DNA,” according to the complaint. Eleven samples held pork DNA and seven cattle DNA, results that run counter to Subway’s marketing claims, it stated.

Maybe Subway is confident in the number of judges available to rule against scientific methodology. Preferring commercials…over proven commercial testing.
