Subway tuna samples contain chicken, pork and cattle DNA, claims amended lawsuit

What’s extra, the criticism alleges, the lab discovered that each one 20 samples contained “detectable sequences of hen DNA,” whereas 11 samples contained pork DNA and 7 included cattle DNA. The presence of different animal DNA, the criticism argues, undermines Subways’ advertising and marketing and labeling, which means clients will get solely “tuna” once they order such a sandwich, salad or wrap. Prospects, the lawsuit alleges, simply have to take a look at the illuminated menu above the counter to see that Subway guarantees tuna to all those that need it.
