This pig-dumping in China can’t reflect good things, and is a kind of a tip-of-the-iceberg thing. Upwards of 6,000 pigs have been dumped into the river serving as Shanghai’s water supply, which

followed police campaigns to curb the illicit trade of pork products harvested from diseased pigs.

Authorities in Shanghai

were stepping up efforts to disinfect public supplies and were testing for six common swine viruses.

Feel better now? Diseased pigs floating in a river are there for all to see. But beneath the surface of the water, and dissolved in it, must be all manner of toxic chemicals, not to mention pathogens. No swimming allowed.
