scares, the aqsiq has declined nationwide testing. local government, for example guangdong authorities, have increased random inspections at poultry farms. they declared to "harshly crack down on the unlawful behaviour of illegally manufacturing, selling and using melamine". contamination and response in 2009–2010 on 2 december 2009, china detained three employees of shaanxi jinqiao dairy company in northwest china suspected of selling 5.25 tons of melamine-laced powdered milk to nanning yueqian food additive company, in guangxi. on 30 december 2009, xinhua reported continuing problems: powder and flavouring products sold by another company involved in the original scandal–the shanghai panda dairy company–were found to contain illegal levels of melamine; the dairy was closed and three of its executives arrested. on 25 january 2010, it was reported that three food companies from hebei, liaoning and shandong provinces had produced melamine tainted products in march and april 2009 and that the three companies were banned from selling products in guizhou. on 10 february 2010 china's state council announced a food safety commission, consisting of three vice premiers and a dozen minister-level officials, to address the nation's food regulatory problems. the group aims to improve government coordination and enforcement and to solve systemic food safety problems. as part of its ongoing effort to find and destroy any melamine-tainted milk remaining on the market, the chinese government announced that it was recalling 170 tons of powdered milk laced with the industrial chemical which was supposed to have been destroyed or buried in 2008 but has recently found to have been repackaged and placed back into the marketplace. in july 2010, xinhua reported that authorities had seized 64 tonnes of dairy product contaminated with melamine from dongyuan dairy factory, in minhe county, in qinghai, after authorities in gansu discovered the contaminated powdered milk. approximately 38 tonnes of raw materials had been purchased from hebei, raising the possibility that traders had bought tainted milk that was supposed to have been destroyed after the 2008 scandal. police have detained the owner and production director of the factory. powdered milk produced in the plant was mainly sold in zhejiang and jiangsu, with only a small amount sold in qinghai. also, in jilin, authorities were testing samples of suspect powdered milk produced in heilongjiang. at the end of june 2010, beijing lowered the minimum protein level for raw milk, from 2.955 to 2.8%, to discourage dairy farmers from attempting to falsify the passing of protein tests. wu heping, secretary general of the heilongjiang dairy industry association noted that between 75% and 90% of raw milk in some provinces had failed to reach the old protein level standard (in place since 1986) in 2007 and 2008. he said that the new standard reflected "the reality of the domestic dairy farm industry". however, insiders believe this will not stop adulteration because milk price still depends on protein content.
