Beijing Sanyuan Foods Company, Ltd. (北京三元食品股份有限公司), a listed dairy producer in China, was chosen by Beijing Olympic Committee as the sole supplier of food and beverage for both the Summer Olympic and the Paralympic. For weeks, Sanyuan was the only listed diary producer that has avoided being associated with China's milk contamination scandal.

On October 7, melamine was reportedly found in Sanyuan's product by the General Administration of Quality Supervision, Inspection and Quarantine, said the Guangdong based newspaper Yangcheng Evening News. The content of the toxic chemical was found to be as high as 10.58 mg/kg in the milk powders manufactured on August 7 by Sanyuan's subsidiary in Qianan, Hebei Province.
