We are asking that they stop saying that they are selling beef.

An Alabama law firm claims in a lawsuit that Taco Bell is using false advertising when it refers to using “seasoned ground beef” or “seasoned beef” in its products.

The meat mixture sold by Taco Bell restaurants contains binders and extenders and does not meet the minimum requirements set by the U.S. Department of Agriculture to be labeled as “beef,” according to the legal complaint.

The class-action lawsuit was filed Friday in federal court in the Central District of California by the Montgomery law firm Beasley, Allen, Crow, Methvin, Portis & Miles. Attorney Dee Miles said attorneys had Taco Bell’s “meat mixture” tested and found it contained less that 35 percent beef.
