McDonald's Corp. (MCD) faces at least three lawsuits claiming the fast-food giant misled the public after it acknowledged earlier this week its French fries contain milk and wheat ingredients, the Wall Street Journal Online reported on Sunday.

The suits were filed by people with celiac disease, who have an intolerance to a protein found in wheat, the Journal said.

McDonald's, based in Oak Brook, Illinois, had previously described the flavoring as safe for people with food allergies and other dietary sensitivities, the Journal said.
