((AP Photo) CHINA OUT) (Newser) – Here's one thing you definitely don't want to find in your water source: 900 or so dead pigs. But that's exactly what Chinese officials have pulled out of a Shanghai river that serves as a city water source. But there's mystery added to the ick factor, notes the AP: City officials aren't sure were the pigs came from, whether they were dumped, or what might have killed them. They say there's no sign of any epidemic, and they emphasize that the water is being tested.
