KFC China, a division of Yum Brands Inc, announced new quality-assurance measures on Monday in a bid to restore brand confidence.

The moves include eliminating more than 1,000 unqualified chicken houses; improving control on poultry suppliers; and implementing timely reporting and communicating with the public, the company said.

Last year, Shanghai's food regulators said that tests conducted by a third-party agency found that eight batches of chicken supplied to KFC by Liuhe Group Co had excessive levels of antibiotics. The fast-food chain said it stopped all supplies from Liuhe in 2012.
