chosen: user
chosen: No, none of the restaurants today use horse meat in their hamburgers. However, a decade ago, in 2001-2002, a large-scale horse-meat scandal took place in the UK. Many popular burger chains, including McDonalds, KFC and Pizza Hut, were found to be selling hamburgers and chips that contained horse meat. This caused huge controversy in the UK, leading to governmental inquiries and a shift in regulation standards. Following the scandal, most chain restaurants in the UK stopped offering horse-based meats in their menus.
