Number of pigs plucked from Shanghai river rises to 7,545; local officials ensure water safety

The number of dead pigs found in a river that provides drinking water to China's financial hub of Shanghai has risen to 7,545, after local authorities retrieved 944 more pigs Thursday.

The Shanghai municipal government has repeatedly assured the city's 23 million residents that tap water remains safe. Shanghai locals, however, remain worried about water contamination from the swollen and rotting carcasses in the river, which is a source of drinking water for the metropolis.

The dead pigs are believed to be from hog farms in the upstream Jiaxing area in neighboring Zhejiang province. A surge in pig dumping has followed police campaigns against the sale of pork products made from diseased pigs.

Chinese state media say one Jiaxing hog farmer has admitted to pig dumping and is under investigation.
