Covington's John Balzano writes on the safety issues with meat production in his blog for Forbes Asia. 

"Safety issues with the meat and meat products in China are causing controversy again. Last year a group of diseased pig carcasses came floating into rivers near Shanghai, causing concern about black markets for meat spreading foodborne illnesses. This time the meat supplier in China was engaged in a variety of unsanitary practices, including adulterating its products with expired meat."
