In 2021, Subway customer Nilima Amin filed a lawsuit alleging that the chain's tuna sandwiches contained absolutely no tuna, leaving many consumers confused.
However, Subway stated in a press release that the claims had no merit and that the tuna sold in its restaurants is wild-caught skipjack and yellowfin.
In February 2021, "Inside Edition" ran a test on Subway’s tuna sandwiches with Applied Food Technologies, and all three samples returned positive as tuna.
