Authorities in Shanghai and east China's Zhejiang Province reassured the public on Friday that no swine epidemic has been detected after more dead pigs were fished out of local rivers.
The municipal government of Jiaxing said another 3,601 dead pigs have been retrieved from rivers and roadsides around the city.
The carcasses of nearly 6,000 pigs were pulled out of the Huangpu River from March 8 to 13. The river provides 22 percent of Shanghai's tap water.
