McDonald's says a scandal over a meat supplier in China is hurting sales in the region and its global sales forecast for 2014 is "at risk."
The world's biggest hamburger chain said in a regulatory filing Monday that there's been "significant negative impact" in China, Japan and other affected markets.
The Oak Brook, Illinois-based company had previously said it expected the sales measure to be "relatively flat" for the year.
A Chinese TV report last month showed workers at one of McDonald's meat suppliers in Shanghai using expired meat. The supplier, Shanghai Husi Food Co., is a division of OSI, a company based in Aurora, Illinois that has been a longtime supplier to McDonald's around the globe. It counts numerous other fast-food chains as its clients.
