There were further black eyes as well. McDonald's was sued in 2001 after it was revealed that for flavoring purposes a small amount of beef extract was being added to the vegetable oil used to cook the french fries. The company had cooked its fries in beef tallow until 1990, when it began claiming in ads that it used 100 percent vegetable oil. McDonald's soon apologized for any "confusion" that had been caused by its use of the beef flavoring, and in mid-2002 it reached a settlement in the litigation, agreeing to donate $10 million to Hindu, vegetarian, and other affected groups. Also in 2001, further embarrassment came when 51 people were charged with conspiring to rig McDonald's game promotions over the course of several years. It was revealed that $24 million of winning McDonald's game tickets had been stolen as part of the scam. McDonald's was not implicated in the scheme, which centered on a worker at an outside company that had administered the promotions.
