A new version of a lawsuit filed against Subway accusing the fast-food restaurant franchise of deceiving the public about its tuna products claims that lab testing shows they contain animal proteins such as chicken, pork, and cattle, and not the advertised “100% tuna.”
The complaint, filed on Monday in U.S. District Court in California by Karen Dhanowa and Nilima Amin, claims that nineteen of 20 tuna samples from Subway restaurants throughout Southern California contained “no detectable tuna DNA sequences whatsoever,” while 20 samples contained “detectable sequences of chicken DNA,” The New York Post reports.
