| Chinese media reports that started circulating 
				on Friday said workers at a Beijing outlet for Subway, which 
				operates globally as a franchise business, changed expiry and 
				production dates on meat, drink and vegetable produce to extend 
				their use.
 "Our headquarters here is now investigating the matter," a 
				Subway spokeswoman said. She said the firm had not reached any 
				conclusions. "We want to investigate what caused the labeling 
				issue and whether or not it was the action of a single 
				franchised outlet."
 
 The issue highlights the difficulty firms have to control food 
				quality and safety in supply chains and outlets in China, which 
				can cause serious headaches with regulators and hit sales.
 
 Earlier this year, a China-based food supplier to McDonald's 
				Corp and Yum Brands Inc was caught up in a scandal over workers 
				allegedly tampering with expiry dates, which pummeled China 
				sales at the fast-food chains.
 
 The Subway spokeswoman said the firm sent teams to inspect its 
				franchises around the country each month and that it gave staff 
				training on food safety and handling produce.
 
 The Beijing food regulator had also launched an investigation, 
				she added.
 
 Food safety scandals in China are all too common, including 
				recycled "gutter oil" for cooking, donkey meat products tainted 
				with fox and one in 2008 involving tainted dairy products that 
				led to the deaths of at least six infants.
 
 Subway, part of Doctor's Associate Inc, has close to 500 outlets 
				in China, according to its official website.
