The Hidden Link Between Factory Farms and Human Illness

You may be familiar with many of the problems associated with concentrated animal feeding operations, or CAFOs. These “factory farm” operations are often criticized for the smell and water pollution caused by all that concentrated manure; the unnatural, grain-heavy diets the animals consume; and the stressful, unhealthy conditions in which the animals live. You may not be aware, however, of the threat such facilities hold for you and your family’s health — even if you never buy any of the meat produced in this manner.

farms are breeding grounds for virulent disease, which can then spread to the wider community via many routes — not just in food, but also in water, the air, and the bodies of farmers, farm workers and their families. Once those microbes become widespread in the environment, it’s very difficult to get rid of them.

A 2008 report from the Pew Commission on Industrial Farm Animal Production, a joint project of the Pew Charitable Trusts and the Johns Hopkins Bloomberg School of Public Health, underscores those risks. The 111-page report, two years in the making, outlines the public health, environmental, animal welfare and rural livelihood consequences of what they call “industrial farm animal production.” Its conclusions couldn’t be clearer. Factory farm production is intensifying worldwide, and rates of new infectious diseases are rising. Of particular concern is the rapid rise of antibiotic-resistant microbes, an inevitable consequence of the widespread use of antibiotics as feed additives in industrial livestock operations.

Scientists, medical personnel and public health officials have been sounding the alarm on these issues for some time. The World Health Organization and the Food and Agriculture Organization (FAO) have recommended restrictions on agricultural uses of antibiotics; the American Public Health Association (APHA) proposed a moratorium on CAFOs back in 2003. All told, more than 350 professional organizations — including the APHA, American Medical Association, the Infectious Diseases Society of America, and the American Academy of Pediatrics — have called for greater regulation of antibiotic use in livestock. The Infectious Diseases Society of America has declared antibiotic-resistant infections an epidemic in the United States. The FAO recently warned that global industrial meat production poses a serious threat to human health.
