A meat packing factory in Liaoyang, a city in Northeast China's Liaoning province, has been found out passing cheap duck meat with toxic additives as mutton and beef, Beijing Times reported on Monday.
The report said more than 40 tons of the meat as well as about a quarter of a ton of additives were seized at the factory by local police.
Some 8.69 grams per kilogram of sodium nitrite was detected in the detained meat products, far exceeding the national standard of 0.3 mg/kg in fresh meat and frozen meat, the report said.
