Taco Bell is introducing an advertising campaign to defend itself against accusations of a lawsuit which alleges that the fast-food chain doesn’t fill its tacos with real beef.

The franchise is placing full-page print ads in major newspapers like The New York Times, Wall Street Journal, USA Today, as well as certain online venues to set the record straight, as company president Greg Creed told The Associated Press.

In large letter, the ads declare: Thank you for suing us. Here's the truth about our seasoned beef. Then, the ad delineates the meat ingredients used in the tacos.

In response to the class-action lawsuit filed late last week in federal court in California, Creed said The lawsuit is bogus and filled with completely inaccurate facts,

The suit accused Taco Bell of false advertising, claiming that the fast-food giant uses a mixture in its burritos and tacos that contains binders and extenders and fails to meet USDA requirements to be labeled beef.

Yum Brands Inc. (NYSE: YUM), Taco Bell's parent, did not state if the media glare on the lawsuit has affected earnings or not.
