TheUnited States is the largest grower of commercial crops that have beengenetically engineered in the world, but not without domestic and international opposition.
Monsanto, based inCreve Coeur, Missouri, in the United States, is the leading producer ofgenetically engineered seed; it sells 90% of the world's GE seeds.[1]

In 1983, environmental groups and protestors delayed the field tests of the genetically modifiedice-minus strain ofP. syringae with legal challenges.[5]Foundation on Economic Trends v. Heckler, 756 F.2d 143 (D.C. Cir. 1985).
In this case, the plaintiff argued both for mandatory labeling on the basis of consumer demand, and that GMO foods should undergo the same testing requirements as food additives because they are "materially changed" and have potentially unidentified health risks. The plaintiff also alleged that the FDA did not follow theAdministrative Procedures Act in formulating and disseminating its policy on GMO's. The federal district court rejected all of those arguments and found that the FDA's determination that GMO's aregenerally recognized as safe was neither arbitrary nor capricious. The court gave deference to the FDA's process on all issues, leaving future plaintiffs little legal recourse to challenge the FDA's policy on GMO's.[6][7](pp. 755–756)Alliance for Bio-Integrity v Shalala, 116 F.Supp.2d 166 (D.D.C. 2000).
Diamond v. Chakrabarty, 447 U.S. 303 (1980), was aUnited States Supreme Court case dealing with whethergenetically modified organisms can bepatented.[8] The Court held that a living, man-made micro-organism is patentable subject matter as a "manufacture" or "composition of matter" within the meaning of thePatent Act of 1952. The fact that the organism sought to be patented is alive is no bar to patentability.
Numerous organizations based in the U.S. oppose or have concerns about genetic engineering for various reasons. Groups such as theCenter for Food Safety, the nonprofit science advocacy groupUnion of Concerned Scientists,Greenpeace and theWorld Wildlife Fund have expressed concerns about theFDA's lack of a requirement for additional testing for GMO's, lack of required labeling and the presumption that GMO's are "generally recognized as safe" (GRAS). Some of these groups have questioned whether the FDA is too close to companies that seek approval for their products.[6]
Although there have been no recorded instances of harm to human health due to the consumption of genetically engineered foods, there is concern over their impact on health. One of the largest food recalls in US history, was theTaco Bell GMO recall, where aBt corn plant not approved for human consumption due its risk as an allergen, had contaminated food products like the tacos at Taco Bell, and a huge percentage of US's seed supply. No health problems were linked to Starlink corn,[9] and subsequent evaluations of the Bt trait determined that there is medium risk to human health.[10]
The USA is the largest commercial grower ofgenetically modified crops in the world.[11] United States regulatory policy is governed by theCoordinated Framework for Regulation of Biotechnology.[12] The United States is not a signatory to theCartagena Protocol on Biosafety.[13] For a genetically modified organism to be approved for release it is assessed by the USDA, the FDA and the EPA. USDA evaluates the plant's potential to become weeds, the FDA reviews plants that could enter or alter the food supply and the EPA regulates the genetically modified plants with pesticide properties. Most developed genetically modified plants are reviewed by at least two of the agencies, with many subject to all three.[14] Final approval can still be denied by individual counties within each state. In 2004,Mendocino County, California became the first and only county to impose a ban on the "Propagation, Cultivation, Raising, and Growing of Genetically Modified Organisms", the measure passing with a 57% majority.[15] (SeeMendocino County GMO Ban)
The Biotechnology Regulatory Services program of theAnimal and Plant Health Inspection Service (APHIS) agency within the USDA is concerned with protecting agriculture and the environment from potential pests under thePlant Protection Act of 2000 (part of theAgriculture Risk Protection Act) and theNational Environmental Policy Act (NEPA).[14][16] Eachtransgenic event is regulated separately as thetransgene insertionlocus varies even when using identicalconstructs and hostgenotypes. This could result in differentexpression patterns or could affect the function of otherendogenous genes within the host. The USDA is responsible for approvingfield trials of GM plants under either the notification or permit procedures.[14] The notification procedure is a streamlined process for the simplest or most familiar genetically engineered plants that meet six criteria (is not anoxious weed, the function of the genetic material is known and characterized, stable integration, no significant risk of creating new viruses and that no animal or human pathogensequences are present).[17] Most field trials are approved under the notification procedure.[14] The permit procedure is much more elaborate and is required for all genetically engineered organisms that do not meet the notification requirements or anyplant-made pharmaceuticals or plant-made industrial products.
APHIS officials are responsible for inspecting the field trials. At least one inspection is carried out for each state listed on a permit, while inspection of field trials authorized by notification is conducted based on the relative risk of each trial.[18] For field trials of organisms that contain pharmaceutical or industrial compounds, inspections are carried out more frequently (five times during establishment and twice yearly after that). If the inspectors are satisfied that there are no regulatory concerns they issue a Notice of Compliance. If the regulations are not being adhered to the inspectors will issue a Notice of Non-Compliance requesting that the deviations be fixed, or for more serious breaches a warning letter requiring a written response and corrective action to be taken within a given time frame.[18] Formal investigations are carried out on developers who may not be adhering to regulations, permit conditions, or other requirements, which can result in civil penalties or criminal charges.
In 1993, the USDA proposal toremove regulatory oversight from GM organisms deemed environmentally benign was approved and four GM plants (Flavr Savr tomato, virus-resistant squash,bromoxynil-tolerant cotton andglyphosate-tolerant soybean) obtained non-regulatory status that year.[14] Non-regulated status means that permits and notifications are no longer required for introductions of this organism. Applicants can petition APHIS for non-regulated status if the GM organism poses no more of a plant pest risk than an equivalent non-GM organism.[19] APHIS will prepare at least two documents (anEnvironmental Assessment and adetermination of non-regulatory status) under the NEPA while considering the application.
Fourfederal district courtsuits have been brought against APHIS challenging their regulation of GM plants. Two involved field trials (herbicide-tolerantturfgrass inOregon; pharmaceutical-producing corn and sugar inHawaii) and the other two were the deregulation of GMalfalfa and GM Sugar Beet.[14] APHIS initially lost all four cases, with the judges ruling they failed to diligently follow the NEPA guidelines. However, the Supreme Court overturned the nationwide ban on GM alfalfa[20] and an appeal court allowed the partial deregulation of GM sugar beet crops.[21] After APHIS preparedEnvironmental Impact Statements for both crops they were deregulated again.[22][23]
TheFDA is responsible for the safety and security of human and animal food and drugs, including any that are genetically modified. The FDA was responsible for approving the first commercialized GMO, Genetech's genetically modified humaninsulin (Humulin) in 1982 and the first commercialized GMwhole food, Calgene'sFlavr Savr tomato in 1994. When evaluating new GM foods or feed the FDA looks for the presence of any new or alteredallergens andtoxicants and examines changes in the levels ofnutritional and anti-nutritional substances.[14] Food and feed that is identical or nearly identical in composition to current products is deemed to besubstantially equivalent[24] and is not required to undergo review by the FDA.[25] The FDA has been criticized for using substantial equivalence, with a major accusation being that FDA review is essentially voluntary as almost all GM products are substantially equivalent.[26] However, all GM food and feed currently on the US market (as of 2008) have undergone a FDAconsultation, where the developer submits the compositional data and FDA scientist compare it to regular food and feed.[14][27]
The FDA consultation focuses on whether the new food or feed contains any new allergens or toxic substances and whether the nutritional components of the food or feed have increased or decreased.[14] The developer submits documentation to the FDA describing the food or feed and a FDA assigned caseworker can then request additional information on expected dietary exposure, in particular if any risk groups (children, elderly etc.) might be exposed. As of 2007, the FDA has not identified any genetically modified foods with unexpected changes in the nutrient composition or levels of allergens or toxic substances.[14] However, allergic proteins have been detected when some GM products have undergone testing.Pioneer Hi-Bred inserted a gene from theBrazil nut intotransgenic soybean resulting in soy with an enhanced nutritional profile. The inserted gene did nottranslate into a known allergen at the time, but when tested with serum from people who areallergic to Brazil nut the allergenic nature of the protein was discovered.[28] The development of the transgenic soybean expressing a Brazil nut allergen was stopped after these tests. The FDA consultation process is relatively (when compared to the other agencies regulating GM) informal and they do not approve new GM products. Instead they issue amemo stating whether the new food is the same as or different from the non-modified variety.[14]
TheCenter for Veterinary Medicine of the FDA regulatesgenetically modified animals in consultation with Centers at the FDA responsible for regulating pharmaceuticals or other medical products derived frombiopharm animals.[29] The FDA also has extra guidelines that apply to genetically modified animals that will be used in themanufacturing and testing of therapeutic products andxenotransplantation.[29] The FDA guidance documents do not establish legally binding laws and are viewed as recommendations, unless specific regulatory or statutory requirements are cited. Any relevant federal, State, or local laws and regulations must also be adhered to.[29]
TheEPA regulates substances withpesticide characteristics, looking at potential threats to human health or the environment.[14] They claim not to regulate the genetically modified plants, but the pesticides produced by the plants or properties that change the usage of applied pesticides . This includes; plants engineered to produce resistance to herbicides (e.g.Roundup Ready), plants that produce their own pesticides (e.g.BT) and virus resistant plants. Authority to regulate the pesticide properties in genetically modified organisms was granted in theFederal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and theFederal Food, Drug, and Cosmetic Act (FFDCA). The EPA published regulations in 1994 and begun acting on them in 1995. In 1994 they proposed the exemption of three categories of genetically modified plants under their regulation. These were plants where the genetic material originated in sexually compatible plants (cisgenic), plants that used physical barriers to prevent the target pest from attaching itself, and plants expressingviral coat proteins to protect against virus infection.[14] In 2001, rules regarding exemption of cisgenic plants had been finalised. The other two proposed exemptions were still under review in 2010.
The EPA evaluated each submission on a case-by-case basis. The EPA assesses data concerning the characterisation of the end-product of the engineered organism (presently all plants evaluated produce proteins), as well as data on mammalian toxicity, effects on non-target organisms and environmental metabolism.[14] For Bt products the producer must also supply an insect resistance management program. For herbicide resistant plants the EPA co-ordinates with the USDA and FDA, but does not regulate the plant itself. Instead it regulates the herbicide and its use on the newcultivar.[14] The EPA examines theconstruct used to transform the plant and the biology of recipient plant. The sequence of the resulting protein must be described, expression pattern and intensity verified and any modifications to the protein reported. The EPA considers the potential allergenicity of the product, issues surrounding gene flow into wild species, possible effects on non-target organisms, likelihood of it persisting in the environment and the potential for insect resistance developing when assessing submissions.[14]
