A lawsuit against Subway is claiming that the popular fast-food chain's tuna sandwiches and wraps don't actually contain real fish.
What Subway calls their tuna is actually a "mixture of various concoctions that do not constitute tuna, yet have been blended together by defendants to imitate the appearance of tuna," according to the complaint obtained by CBS News.
The lawsuit was filed last week in the U.S. District Court for the Northern District of California on behalf of California residents Karen Dhanowa and Nilima Amin.
According to Alex Brown, the attorney who is representing Dhanowa and Amin in the case, told CBS MoneyWatch they are conducting tests to figure out what ingredients are used in Subway's tuna.
However, the company is denying the claims in the lawsuit. When CBS MoneyWatch reached out to their team, Maggie Truax, Subway's director of Global PR, responded in an email stating:
"There simply is no truth to the allegations in the complaint that was filed in California. Subway delivers 100% cooked tuna to its restaurants, which is mixed with mayonnaise and used in freshly made sandwiches, wraps and salads that are served to and enjoyed by our guests."
If Dhanowa and Amin's lawsuit is certified as a class-action, it could go on to represent thousands of customers who have purchased tuna from any of Subway's 2,266 California locations after January 21, 2017.
This isn't Subway's first time in court over concern about its products.
In 2017 a class-action settlement claimed the chain's footlong subs were an inch shorter than the length advertised.
And Ireland's Supreme Court ruled in September that Subway's bread could not legally be called bread due to its high sugar content.
