Factory Farm Conditions Are Bad for People Too
The problem: Livestock in this country produce between 3 and 20 times more waste than people in the U.S. produce, according to a 2005 report issued by the Environmental Protection Agency (EPA). That’s as much as 1.2-1.37 billion tons of manure a year. Some estimates are even higher.
Manure can contain “pathogens such as E. coli, growth hormones, antibiotics, chemicals used as additives to the manure or to clean equipment, animal blood, silage leachate from corn feed, or copper sulfate used in footbaths for cows,” according to a 2010 report by the National Association of Local Boards of Health. Though sewage treatment plants are required for human waste, no such treatment facility exists for livestock waste.
Since this amount far exceeds what can be used as fertilizer, animal waste from factory farms typically enters massive, open-air waste lagoons, which spread airborne pathogens to people who live nearby. If animal waste is applied as fertilizer and exceeds the soil’s capacity for absorption, or if there is a leak or break in the manure storage or containment unit, the animal waste runs off into oceans, lakes, rivers, streams and groundwater.
