OAK BROOK, ILL. — Despite improved sales in the United States, global comparable sales at McDonald’s Corp. decreased 1.9% in January. The primary reason was a 9.5% comparable decrease in the Asia/Pacific region, specifically China, due to media attention related to antibiotics in chicken.

“McDonald’s is focused on satisfying the needs of each and every customer visiting our restaurants in search of great-tasting food and beverages, outstanding service and everyday value,” said Don Thompson, president and chief executive officer. “While January’s results reflect today’s challenging environment and difficult prior-year comparisons, I am confident our unwavering commitment to delivering an exceptional restaurant experience will enhance our brand’s relevance and drive long-term results.”

U.S. comparable sales were up 0.9% in January on premium, core and value options and the addition of the Grilled Onion Cheddar burger to the dollar menu.

European sales decreased 2.1% as positive results in the United Kingdom and Russia were offset by performance in Germany, France and other markets.

McDonald’s said comparable sales decreased 9.5% in Asia/Pacific, Middle East and Africa on weakness in Japan and negative results in China due to the timing of the Chinese New Year and the impact of consumer reaction to the chicken supply chain issue in the country.
