The Chinese outlets of McDonald’s and KFC have stopped using meat from a Shanghai company after a local television news program accused the supplier of using chicken and beef past their expiration date, triggering an investigation by local food safety officials.

The program, aired on Shanghai-based Dragon TV on Sunday evening, showed hidden camera footage of workers at a meat-processing facility operated by Shanghai Husi Food using out-of-date chicken and beef to make burger patties and chicken products for McDonald’s and KFC, in some cases scooping up meat that had fallen onto the assembly line floor and throwing it back into a processing machine.

In response, the Chinese units of McDonald’s and KFC both said in news releases posted from their official Sina Weibo social messaging accounts that they had halted use of all products from Shanghai Husi, which is owned by the OSI Group, based in Aurora, Ill.
