In a statement, the Shanghai municipal government said that the water in Huangpu River, which is a major source of drinking water for Shanghai, was safe. It also said that no diseased pork had been detected in markets.

The government statement said that the number of pigs being salvaged from the river appeared to be decreasing. Laboratory tests have identified that some of the pigs had porcine circovirus, a common disease that affects pigs but does not affect humans. Reports suggest the dead pigs may have been dumped from pig farms in Jiaxing, upstream of Shanghai.
