The Oak Brook, Illinois-based chain says the figure was down 0.6 per cent globally. That included a 0.7 per cent increase in the US, where it recently introduced its chicken McWraps to attract more customers in their 20s and 30s.
But it fell 2.4 per cent in Europe, its biggest market by sales. In the region encompassing Asia, the Middle East and Africa, it was down 2.9 per cent. The chain blamed the impact of the avian flu in China for the decline, as well as softness in Japan and Australia.
After years of outperforming rivals, McDonald's has been struggling to increase sales as it faces increasing competition, changing eating habits and slow growth in the broader restaurant industry. CEO Don Thompson, who took over the top spot this summer, has said that the company will focus on emphasizing value to capture market share in the tough environment.
Sales at restaurants open at least 13 months is a key metric because it strips out the impact of newly opened and closed locations.
