If you’ve ever spent time roaming through the aisles of a grocery store, you have undoubtedly seen food labeled “organic.” You may even have purchased organic food, despite the fact that it is generally more expensive than conventionally grown food. Some people prefer organic food because they believe it is healthier and tastes better. Others buy it because they think organic food is safer to eat. Still others believe organic food is produced in a way that is healthier for the environment and safer for farmworkers. Are these beliefs accurate? What exactly does the organic food label mean?
How did the organic food movement begin?
The notion of organic food emerged in the 1940s, when farmers first started using synthetic pesticides in agriculture. Three decades later, interest in organic food increased as concerns about environmental contaminants became more widespread. Organic food enthusiasts wanted food that was free of chemicals, including pesticides. At the same time, the popularity of food grown locally on small farms was increasing. The push for organic produce in the 1970s was part of a counterculture movement against the farming practices of large-
An organic farmer is fundamentally concerned with the health of the soil. He or she will work hard to ensure that the organic matter content, base saturation, and cation exchange capacity of the soil will increase each year. Actions that will degrade the soil or promote erosion are carefully avoided (FIGURE SA5.1).
Today, organic food is much more common and appeals to people from all walks of life. Indeed, organic farming has increased rapidly during the past decade. According to the U.S. Department of Agriculture, the number of acres of organic farmland increased more than fivefold from 1995 to 2011. The states with the most land devoted to organic farmland are California, Wyoming, Oregon, Texas, and New Mexico. In 2011, there were about 2.2 million ha (5.4 million acres) of organic cropland and pastureland in the United States. But although organic food has been the fastest-

The rise in popularity of organic products has brought increased pressure to define what exactly it means to be organic. Without government guidelines, anyone could claim to be selling organic food. In 1990, the U.S. Department of Agriculture (USDA) began to develop guidelines for organic food. Its goal was to set national organic certification standards that would assure consumers that the food was produced and processed with minimal use of chemicals. Food that met these standards could carry the USDA Organic seal (FIGURE SA5.2).
In 1995, the USDA determined that “Organic agriculture is an ecological production management system that promotes and enhances biodiversity, biological cycles, and soil biological activity. It is based on minimal use of off-
Pest control is perhaps one of the greatest challenges in organic farming. Agricultural pests include weeds that compete with the crops, insects that eat the crops, and fungal pathogens that can kill the crops. Organic farmers are required to try to control pests without synthetic pesticides. Such efforts can include mechanically destroying weeds and using plant-
Having standards for organic food is effective only if those standards are enforced. One of the important functions of the USDA’s National Organic Program is to conduct inspections of organic food producers and processors to ensure that organic food meets the national standards. Since 1990, the government has allowed inspections to be conducted by independent companies that are hired by producers and processors to inspect organic farms and factories to ensure that the organic standards are being met.
As part of this effort, the certifying companies were required to conduct spot checks. In 2010, the USDA announced that it had failed to enforce the spot check requirement and that, as a result, many of the largest independent certifiers had been conducting spot checks on organic food only if they suspected a problem. When problems were not suspected, producers could operate for years without any spot checks. In fact, some growers had been selling nonorganic food under the USDA Organic seal and obtaining a higher price for their products. In response, the federal government announced in 2010 that the funding and staff of the National Organic Program would nearly double to ensure that the certifying companies were conducting the required spot checks.
Does organic food mean family farms?
Most organic food production was originally conducted on small family farms. As we saw in Chapter 11, organic farming methods can require more labor, time, and money than conventional methods, so the price of organic food can be significantly higher. As farmers have learned, however, many consumers are willing to pay a premium for what they believe to be a premium product. This consumer behavior has attracted the attention of large factory farms owned by corporations, which have begun to conduct large-
Although organic farms have a history of being small farms, there is no inherent reason why large farms cannot grow organic food (FIGURE SA5.3). An increasing number of corporations have decided to enter the business of organic food production. One of the most significant events to drive this movement occurred in 2006 when Wal-

As more factory farms entered the organic food business, there was increasing pressure to permit the use of some nonorganic and synthetic chemicals during the production stage, when the food from the field is turned into a form that can be sold in the grocery store. Proponents of the rule change, including agribusinesses, argued that many processed foods, such as frozen meals, could not be made in an organic version unless the rules about additives were changed. Opponents argued that if processed foods could not be made without additives, then processed foods should not be certified as organic. In 2002, the USDA designated several nonorganic and synthetic additives as permissible in organic processed foods. Permitted nonorganic additives include citric acid, pectin, and cornstarch. Synthetic chemicals permitted in the processing of organic foods include alcohol (used for disinfecting machinery) and aspirin (used for medical treatment of animals). The number of nonorganic additives has increased from 77 additives in 2002 to 250 additives in 2013.
What doesn’t the organic label mean?
The USDA definition of “organic” does not match what many people think or hope “organic” should mean. For example, many people associate organic food with small family farms, but as we have seen, organic food can be grown on farms of all sizes. The USDA organic seal therefore tells us nothing about the size of the farm that grew the food. Nor does the seal tell us anything about the safety of the food, including whether it contains fewer dangerous food-
In response to public demand, farmers sometimes use food labels that go beyond the federal requirements for organic certification. They may include information about humane treatment of animals, the conditions and wages of the farmworkers, and whether genetically modified organisms were used. Such detailed labels have seen growing popularity.
Although the USDA organic certification has a somewhat narrow definition, it does offer a number of important benefits. As reported in a 2012 study by researchers at Stanford University, there is no evidence that organic food is healthier for humans to eat than nonorganic food. However, the certification program at least provides a standardized set of requirements so that informed consumers understand what they are buying. Given the reduction in synthetic pesticide use, the program also allows consumers to support farming practices that are much better for soils and ecosystems and better for farmworkers—

For many people, organic farming involves far more than the reduction of pesticide and fertilizer use. Organic farming is also a method of caring for the land in a manner that will benefit landscape ecology and sustain crop production for many years.
