Pond water
Soon after the gutter oil gang was sentenced, authorities arrested seven people in southern Guangdong province for injecting dirty pond water into lamb meat to swell its weight as a means to increase its price, state television reported.
According to the investigation, the gang slaughtered up to 100 sheep per day at an illegal warehouse, pumping brackish water into the meat before it was sold at markets, food stalls and restaurants in major cities including Guangzhou and Foshan.
