Organic food, also known as ecological or biological food, refers to foods and beverages produced using methods that comply with the standards of organic farming. Standards vary worldwide, but organic farming features practices that cycle resources, promote ecological balance, and conserve biodiversity. Organizations regulating organic products may restrict the use of certain pesticides and fertilizers in the farming methods used to produce such products. Organic foods are typically not processed using irradiation, industrial solvents, or synthetic food additives.

In the 21st century, the European Union, the United States, Canada, Mexico, Japan, and many other countries require producers to obtain special certification to market their food as organic. Although the produce of kitchen gardens may actually be organic, selling food with an organic label is regulated by governmental food safety authorities, such as the National Organic Program of the US Department of Agriculture (USDA) or the European Commission (EC).

From an environmental perspective, fertilizing, overproduction, and the use of pesticides in conventional farming may negatively affect ecosystems, soil health, biodiversity, groundwater, and drinking water supplies. These environmental and health issues are intended to be minimized or avoided in organic farming.

Demand for organic foods is primarily driven by consumer concerns for personal health and the environment, such as the detrimental environmental impacts of pesticides. From the perspective of scientists and consumers, there is insufficient evidence in the scientific and medical literature to support claims that organic food is either substantially safer or healthier to eat than conventional food. Organic agriculture has higher production costs and lower yields, higher labor costs, and higher consumer prices as compared to conventional farming methods.

Meaning, history and origin of the term

For the vast majority of its history, agriculture can be described as having been organic; only during the 20th century was a large supply of new products, generally deemed not organic, introduced into food production. The organic farming movement arose in the 1940s in response to the industrialization of agriculture.

In 1939, Lord Northbourne coined the term organic farming in his book Look to the Land (1940), out of his conception of "the farm as organism", to describe a holistic, ecologically balanced approach to farming—in contrast to what he called chemical farming, which relied on "imported fertility" and "cannot be self-sufficient nor an organic whole". Early soil scientists also described the differences in soil composition when animal manures were used as "organic", because they contain carbon compounds, whereas superphosphates and Haber process nitrogen do not. Their respective use affects humus content of soil.Paull, John (2011) "The Betteshanger Summer School: Missing link between biodynamic agriculture and organic farming", Journal of Organic Systems, 2011, 6(2):13–26. This is different from the scientific use of the term "organic" in chemistry, which refers to a class of molecules that contain carbon, especially those involved in the chemistry of life. This class of molecules includes everything likely to be considered edible, as well as most pesticides and toxins too, therefore the term "organic" and, especially, the term "inorganic" (sometimes wrongly used as a contrast by the popular press) as they apply to organic chemistry is an equivocation fallacy when applied to farming, the production of food, and to foodstuffs themselves. Properly used in this agricultural science context, "organic" refers to the methods grown and processed, not necessarily the chemical composition of the food.

Ideas that organic food could be healthier and better for the environment originated in the early days of the organic movement as a result of publications like the 1943 book The Living Soil and Farming and Gardening for Health or Disease (1945).

In the industrial era, organic gardening reached a modest level of popularity in the United States in the 1950s. In the 1960s, environmentalists and the counterculture championed organic food, but it was only in the 1970s that a national marketplace for organic foods developed.

Early consumers interested in organic food would look for non-chemically treated, non-use of unapproved pesticides, fresh or minimally processed food. They mostly had to buy directly from growers. Later, "Know your farmer, know your food" became the motto of a new initiative instituted by the USDA in September 2009. Personal definitions of what constituted "organic" were developed through firsthand experience: by talking to farmers, seeing farm conditions, and farming activities. Small farms grew vegetables (and raised livestock) using organic farming practices, with or without certification, and the individual consumer monitored. Small specialty health food stores and co-operatives were instrumental to bringing organic food to a wider audience. As demand for organic foods continued to increase, high-volume sales through mass outlets such as supermarkets rapidly replaced the direct farmer connection.Today, many large corporate farms have an organic division. However, for supermarket consumers, food production is not easily observable, and product labeling, like "certified organic", is relied upon. Government regulations and third-party inspectors are looked to for assurance.

In the 1970s, interest in organic food grew with the rise of the environmental movement and was also spurred by food-related health scares like the concerns about Alar that arose in the mid-1980s.

Legal definition+

Organic food production is distinct from private gardening. In the EU, organic farming and organic food are more commonly known as ecological or biological, or in short "eco" and "bio".Labeling, article 30 and Annex IV of Regulation (EU) 2018/848 of the European Parliament and of the Council of 30 May 2018 on organic production and labeling of organic products and repealing Council Regulation (EC) No 834/2007.

Currently, the European Union, the United States, Canada, Japan, and many other countries require producers to obtain special certification based on government-defined standards to market food as organic within their borders. In the context of these regulations, foods marketed as organic are produced in a way that complies with organic standards set by national governments and international organic industry trade organizations.

In the United States, organic production is managed in accordance with the Organic Foods Production Act of 1990 (OFPA) and regulations in Title 7, Part 205 of the Code of Federal Regulations to respond to site-specific conditions by integrating cultural, biological, and mechanical practices that foster cycling of resources, promote ecological balance, and conserve biodiversity. If livestock are involved, the livestock must be reared with regular access to pasture and without the routine use of antibiotics or growth hormones.

Processed organic food usually contains only organic ingredients. If non-organic ingredients are present, at least a certain percentage of the food's total plant and animal ingredients must be organic (95% in the United States, Canada, and Australia). Foods claiming to be organic must be free of artificial food additives, and are often processed with fewer artificial methods, materials and conditions, such as chemical ripening, food irradiation, solvents such as hexane, and genetically modified ingredients. Pesticides are allowed as long as they are not synthetic.Staff, National Pesticide Information Center. Organic Pesticide Ingredients. However, under US federal organic standards, if pests and weeds are not controllable through management practices, nor via organic pesticides and herbicides, "a substance included on the National List of synthetic substances allowed for use in organic crop production may be applied to prevent, suppress, or control pests, weeds, or diseases". Several groups have called for organic standards to prohibit nanotechnology on the basis of the precautionary principlePaull, J. & Lyons, K.

A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials. National Academies Press: Washington DC. 2012. The use of nanotechnology-based products in the production of organic food is prohibited in some jurisdictions (Canada, the UK, and Australia) and is unregulated in others.Staff, The Organic & Non-GMO Report, May 2010. Canada bans nanotechnology in organics.Canada General Standards Board. Organic Production Systems General Principles And Management Standards (CAN/CGSB-32.310-2006) .

In the United States, there are four different levels or categories for organic labeling:"USDA organic: what qualifies as organic?" Massage Therapy Journal Spring 2011: 36+. Academic OneFile. "100% Organic": This means that all ingredients are produced organically. It also may have the USDA seal. "Organic": At least 95% or more of the ingredients are organic. "Made With Organic Ingredients": Contains at least 70% organic ingredients. "Less Than 70% Organic Ingredients": Three of the organic ingredients must be listed under the ingredient section of the label. In the U.S., the food label "natural" or "all natural" does not mean that the food was produced and processed organically..

Environmental sustainability

From an environmental perspective, fertilizing, overproduction and the use of pesticides in conventional farming has caused, and is causing, enormous damage worldwide to local ecosystems, soil health, biodiversity, groundwater and drinking water supplies, and sometimes farmers' health and fertility.

Organic farming typically reduces some environmental impact relative to conventional farming, but the scale of reduction can be difficult to quantify and varies depending on farming methods. In some cases, reducing food waste and dietary changes might provide greater benefits. A 2020 study at the Technical University of Munich found that the greenhouse gas emissions of organically farmed plant-based food were lower than conventionally farmed plant-based food. The greenhouse gas costs of organically produced meat were approximately the same as non-organically produced meat. However, the same paper noted that a shift from conventional to organic practices would likely be beneficial for long-term efficiency and ecosystem services, and probably improve soil over time.

Recent research has suggested that the usage of organic fertilizers and cover crops can enhance soil organic carbon, nutrient cycling, and biodiversity. Simultaneously, it could also reduce greenhouse gas emissions when it is managed effectively. These practices contribute to climate change mitigation and sustainable agriculture when improving soil resilience and long-term fertility. [Khan et al., 2024]
