Officials in Chongqing have released the last two Wal-Mart (WMT.NYSE) employees detained over a pork mislabeling scandal last October, causing a two-week closure of a dozen stores in the city, Reuters reported. Wal-Mart spokesman Anthony Rose said the last two employees were discharged last week but declined to give further details. “All of our detained associates have been released,” he said. Wal-Mart hired Greg Foran as president and chief executive of Wal-Mart China to replace Ed Chan, who resigned in October following allegations that the retailer sold ordinary pork as an organic variety. The company’s stores in Chongqing were shut for two weeks following the incident.
