June 25, 2021 — Subway Restaurants has come to the defense of its tuna products and said it utilizes 100 percent wild tuna, after facing a class-action lawsuit and a New York Times report that claimed testing found no tuna DNA in the restaurant chain’s tuna sandwiches.
The DNA testing utilized by the lab in the New York Times report is not accurate for canned and/or processed tuna, according to both Subway and the founder of a top DNA testing lab for cooked and processed tuna who spoke to SeafoodSource.
