(ECNS) -- Three disposal sites where diseased pigs were dumped have been excavated and refilled after disinfection work was completed on Friday afternoon with no infectious diseases found, according to a circular released by the Huzhou government in East China's Zhejiang Province.
The authority said over 223.5 tons of decomposed carcasses and sludge have been excavated and will be incinerated.
Local police found Huzhou Industrial and Medical Waste Treatment Co. had shipped pigs that died of disease to a landfill rather than for incineration between 2013 and 2014.
Digging and cleaning work began on Sept 1. A sample test by the city's agricultural department said that no human-infecting pig diseases such as H5 and H7 bird flu viruses and foot-and-mouth disease had been found.
The local environmental service center will carry out an environment impact assessment, according to Xinhua News Agency. The Zhejiang provincial government has also sent inspectors to oversee the treatment process.
Five people have been detained following the inquiry.
