A federal judge is allowing a woman to file a lawsuit against Subway after she says the restaurant chain misled her by claiming their sandwiches contain "100% tuna."
Subway sought to dismiss the lawsuit, which claims lab testing shows the tuna contains animal products such as chicken, pork and cattle, but a judge determined the case should move forward.
The lawsuit, filed in U.S. District Court, claims that Subway has "been making false and misleading representations about tuna being used as an ingredient." A study of 20 Subway tuna samples found that 19 samples had "no detectable tuna DNA sequences" while all 20 contained detectable chicken DNA, 11 contained pork DNA and 7 contained cattle DNA, the lawsuit alleges.
Subway, which previously called the lawsuit "meritless," maintains it serves 100% tuna.
