Regular duck feed (R) is compared with feed mixed with Sudan IV, an illegal substance in China, in this TV grab. On Sunday CCTV ran a report that claimed the red yolk duck eggs from Bai Yang Dian on the Beijing market were laid by ducks that had been fed Sudan IV, an industrial dye that may cause cancer in humans if eaten. Some farmers in Bai Yang Dian, Hebei Province are using the dye to make red-yolk eggs in an attempt to attract customers. [CCTV photo]
