As of Monday, more than 1,000 dead ducks have been fished out of the Pengshan section of the Nanhe River in Sichuan province, China's official Xinhua news agency reported.
The bodies have been disinfected, put in plastic woven bags and buried almost 10 feet under ground in a designated area, Liang Weidong, an official with the county's publicity office, said Monday.
Liang said the birds have been handled properly and pose no threat to local residents and livestock.
The ducks are believed to have originated upstream and then accumulated in Pengshan due to a lack of water in the river, China Daily reported. The cause of their death is unknown.
