Reacting to public concern after the government said there was a possible link between eating beef contaminated with so-called "mad cow' disease and a fatal brain condition, McDonald's said in a statement it welcomed government moves to tighten controls on the supply and quality of beef.
"All McDonald's food products are made from highest quality ingredients," it said. "McDonald's only uses prime cuts of boneless beef in which BSE has never been detected."
"McDonald's never has and never will use offal in the production of its hamburgers," the statement said.
"McDonald's standards exceed UK government requirements by also regularly auditing their suppliers themselves.
