Beijing: Fifty-two people were arrested in China for selling cooking oil made from the leftovers collected from restaurant gutters, a media report said Tuesday.
They were held in Jiangxi province.
Over 2,000 tonnes of gutter oil were produced illegally in the province`s Nanchang county since 2010, police said.
The manufacturers sell the oil to wholesale firms which then supply it to markets and restaurants, China Daily reported.
China had launched a nationwide campaign against the sale of gutter oil in August. By November, over 700 people involved in the illegal business were detained in 28 provinces and municipalities, officials said.
