Dale Keiger explores the connection between factory farming and disease:
The United States Department of Agriculture (USDA) estimates that livestock and poultry produce 335 million tons of manure per year, which is one way resistant pathogens get out of animals and into the environment. That's 40 times as much fecal waste as humans produce annually. Farms use it for fertilizer and collect it in sheds and manure lagoons, but those containment measures do not prevent infectious microbes from getting into the air, soil, and water. They can be transported off the farms by the animals themselves, houseflies, farm trucks, and farm workers, and by spreading manure on other fields. Out in the environment, they form a sort of bank of genetic material that enables the spread of resistance.
