Two Californians claim they’ve found something fishy with Subway’s tuna—it doesn’t actually contain tuna, but other fish species.

A new version of a lawsuit originally filed in January alleges that Subway misled the public about its tuna sandwiches and claims that the tuna sampled has trace amounts of chicken, pork and cattle DNA.

In their second amended proposed class-action complaint filed earlier this week in federal court in Northern California, Karen Dhanowa and Nilima Amin claim that out of 20 samples tested, 19 had no detectable tuna DNA sequences.

All 20, the complaint states, had detectable sequences of chicken DNA, 11 samples had detectable pork DNA and seven had detectable cattle DNA. The samples were tested at the Department of Ecology and Evolutionary Biology at the University of California, Los Angeles, the complaint says.

A Subway spokeswoman denied the claims, saying the sandwich shop’s tuna is “high-quality,” ” wild-caught” and “100% tuna.”
