A San Francisco area talk show host has filed a lawsuit against McDonald's Corp accusing the world's largest fast-food restaurant company of failing to switch to healthier lower-fat cooking oil as it had pledged.
McDonald's said it had not yet seen of a copy of the lawsuit, filed on Thursday in federal district court in San Francisco.
The lawsuit was filed on behalf of radio talk show host Katherine Fettke by attorney Stephen Joseph, who also has sued to stop Kraft Foods Inc from selling its popular Oreo cookies in California to children because the cookies contain trans fatty acids.
