Factory Farms
by RtE Legal Intern Leah Berntsen

Factory Farms
Factory farms, or Concentrated Animal Feeding Operations (CAFOs), are large-scale farming operations that densely confine cattle, swine, sheep, or poultry. CAFOs produce large numbers of animals more quickly and for less money, but the real costs of these operations are generally ignored. CAFOS can have disastrous impacts on the environment, public health, animal health and family farms.

Family Farms
As the number of CAFOs has increased over the last 20 years, family farms are forced out of business by their inability to compete. From 1982 to 2002, the number of farms and ranches decreased by 330,000. The loss of family farms not only affects food production but also economy and society. Family farms support and create rural economies and communities. In addition, family farms engage in crop rotation integrated with livestock production resulting in biological diversity and ecological resilience not found in CAFOs. Family farms also provide urban people with a social connection to farming and rural communities. This place-based identification of food products provides intrinsic value beyond food production alone. Dave Matthews has noted in his support of family farms: "There was also this growing urge to sustain the family farmer. Those things became apparent to me in my interest in the quality of food I was eating and soon thereafter the quality of food my family was eating. I'm involved for the big picture, and it seems the natural battle to support. It is one that is concerned on so many different levels with things I am concerned with: the health of the environment, the health of citizens, the health of the farm, the health of our culture. All of those fall on a very basic level right at how we grow food and what we eat. I can't think of a more universal purpose than the support and nurturing of healthy food from healthy farms."

Environmental and Health Effects
CAFOs produce an immense amount of manure and other animal waste that pollute soil, air and water. CAFO animal waste releases ammonia, nitrous oxide, nitric oxide, methane, volatile organic compounds, hydrogen sulfide and particulates into the air as well as emitting a nasty odor. Nitrous oxide, methane and some volatile organic compounds contribute to the greenhouse effect, and nitric oxide can result in decreased productivity of crops and terrestrial ecosystems. In addition, ammonia, nitrous oxide and nitric oxide create a "nitrogen cascade" as the nitrogen transforms into different compounds as it moves through the environment. In the air, nitrogen decreases atmospheric visibility and increases acidity in precipitation. In the soil, excess nitrogen can increase soil acidity, decrease biodiversity and increase or decrease ecosystem productivity. In the water, nitrogen can increase surface water acidity and lead to coastal eutrophication. These compounds also affect human health. The effects vary depending on the compound, concentration and exposure. Ammonia, hydrogen sulfide and particulates can all cause eye, nose and throat irritation, headaches, fatigue, nausea, diarrhea and respiratory problems for people living near factor farms. Employees inside factor farms have died from exposure to these compounds.

CAFO animal waste also directly affects water and soil quality. CAFOs produce approximately 575 billion pounds of manure annually. To reduce cost of bedding, animals are kept on concrete or slatted floors and manure is flushed with water. This liquid manure is stored in lagoons or sprayed on fields. While manure is a valuable fertilizer, the amount applied vastly exceeds the necessary level of fertilizer and the excess pollutes nearby ground and surface water sources. Lagoons also impair water quality though spills and leaks. The resulting overflow pollutes the water with nitrogen, phosphorus, ammonia, bacteria, antibiotics and hormones. This pollution contaminates drinking water sources, causes algae blooms and fish kills.

In addition, the animals are given antibiotics and hormones to accelerate growth and combat diseases compounded by such close confinement. These uses account for an estimated 13 million pounds of antibiotics annually compared to 3 million pounds prescribed for human use. And, because most of antimicrobials are identical, or nearly, to drugs used in human medicine , the overuse has resulted in new strains of virulent bacteria resistant to antibiotics endangering public health. Hormones are also a danger to human health by disrupting natural cellular development. Further, both antibiotics and hormones not absorbed by the animal end up in manure and, as discussed above, contaminate ground and surface water affecting the environment and public health.

What Can You Do
Know your food by asking how and where your food was produced, and support local grocers and restaurants that source their food from family farmers. Or, buy direct from local family farmers. Find a farmers market at http://www.ams.usda.gov/farmersmarkets. In addition, share information about factory farms with friends and family and encourage them to support family farmers.
