A San Francisco radio host is suing McDonald’s over its continued use of trans fat cooking oils.


Katherine Fettke’s suit demands the company inform consumers that it has not fulfilled a pledge to develop healthier alternatives.


Fettke claims McDonald’s broke its September 2002 promise to dramatically cut trans fats in its menu by February 2003, and wants McDonald’s “to switch as soon as possible”. Earlier this year, McDonald’s said switching oils would take longer than expected and required further testing.


Fettke is represented by Laurence Joseph, founder of bantransfats.com, who last year sued Kraft over its Oreo Cookies. The suit was dropped when Kraft announced it would soon reduce or eliminate trans fat in Oreos.
