China: pig carcasses found floating in Hunan river

Scores of dead pigs have been retrieved from a Central China waterway, just weeks after thousands were discovered in Shanghai's Huangpu River.

Authorities have been pulling the carcasses from Liuyang River in Hunan province since Saturday. More than 70 pigs had been retrieved as of Sunday, but an official figure has yet to be released.

The district environmental protection bureau said it will closely monitor the river's water quality to guarantee residents' safety.
