A very interesting read on the nature of pollution from pig farms in the United States, the level of contamination, and possible damages to the environment.
A lot of pig shit is one thing; a lot of highly toxic pig shit is another. The excrement of Smithfield hogs is hardly even pig shit: On a continuum of pollutants, it is probably closer to radioactive waste than to organic manure. The reason it is so toxic is Smithfield's efficiency. The company produces 6 billion pounds of packaged pork each year. That's a remarkable achievement, a prolificacy unimagined only two decades ago, and the only way to do it is to raise pigs in astonishing, unprecedented concentrations.
Industrial pig waste also contains a host of other toxic substances: ammonia, methane, hydrogen sulfide, carbon monoxide, cyanide, phosphorous, nitrates and heavy metals. In addition, the waste nurses more than 100 microbial pathogens that can cause illness in humans, including salmonella, cryptosporidium, streptocolli and girardia.
