Hong Kong (CNN) - At least 2,800 dead pigs have been fished from a Shanghai river since Friday but authorities insist that tap water in the city is still safe to drink.

State news agency Xinhua said labels tagged to the pigs’ ears indicated they came from the upper waters of the Huangpu River, which flows through the center of Shanghai and is a source of the city’s drinking water.

It’s not clear why the pigs had been dumped in the river, though local media reported earlier this month that a disease had killed thousands of pigs in a village south of Shanghai.

“We will continue to trace the source, investigate the cause, co-operate with neighboring areas and take measures to stop the dumping of pigs into rivers,” the Shanghai Municipal Agricultural Commission said in a statement posted on their website on Monday.

As of Sunday, water quality on the Songjiang section of the river, where most of the pigs were found, remained normal and the incident has had “no significant effect on tap water supply,” the commission added.

The agricultural commission said it had tested organ samples from the pig carcasses and the results suggested the animals had contracted a type of porcine circovirus.
