“Escherichia colia O157:H7 is a relatively new strain of the common intestinal bacteria (no one had seen it before 1980) that thrives in feedlot cattle, 40 percent of which carry it in their gut. Ingesting as few as ten of these microbes can cause a fatal infection; they produce a toxin that destroys human kidneys.” CattleBacteriaFactory FarmingFeedlots Book:The Omnivore's Dilemma: A Natural History of Four Meals Source: The Omnivore's Dilemma: A Natural History of Four Meals
“I asked the feedlot manager why they didn't just spray the liquefied manure on neighboring farms. The farmers don't want it, he explained. The nitrogen and phosphorus levels are so high that spraying the crops would kill them. He didn't say that feedlot wastes also contain heavy metals and hormone residues, persistent chemicals that end up in waterways downstream, where scientists have found fish and amphibians exhibiting abnormal sex characteristics.” EnvironmentPollutionManureFactory FarmingFeedlots Book:The Omnivore's Dilemma: A Natural History of Four Meals Source: The Omnivore's Dilemma: A Natural History of Four Meals
