The bodies were found floating in the river water yesterday and the local authorities are still retrieving dead pigs to avoid water contamination, state-run Xinhua news agency reported.
The bureau said the water quality has not been affected. To ensure tap water safety, local environmental protection and water supplies authorities have beefed up the quality examination of water disinfection process.
The Shanghai Agriculture Committee have also carried out a bio-safety treatment on the retrieved dead pigs. It is now investigating that from where these pigs have come.
The committee said that so far it has not received any reports of animal epidemic outbreaks in the city.
