Husi faced unethical practice claims in 2013

Shanghai Husi Food, the US-owned Chinese food supplier at the center of a meat safety scandal, won a court case earlier this year against a former quality control officer whose claims included that he was made to forge meat production dates.

Wang Donglai, who worked at the company from 2007 to 2013, sought about 38,000 yuan ($6,100) in compensation for damage to his health from exposure to chlorine used as a cleaning agent by the meat processor.

He also sought to terminate his contract, claiming he was forced to work overtime and made to do "unethical work" that violated food safety laws, court documents showed.
