L'augmentation de la concentration des substances toxiques bioaccumulés dans les organismes supérieurs sur la chaîne alimentaire grâce à un stockage préférentiel de toxiques chimiques dans les parties du corps comestibles. Par exemple, les pesticides chlorés se concentrent dans la graisse et la peau des poissons dans les lacs contaminés et cours d'eau et sont bioamplifié lorsque les poissons sont mangés par des poissons plus gros et peut-être finalement de mammifères ou d'oiseaux de proie.

The generic term for any living matter that can be converted into usable energy through biological or chemical processes. It encompasses feedstocks such as agricultural crops and their residues, animal wastes, wood, wood residues and grasses, and municipal wastes.
Industry:Agriculture
A pesticide that is biological in origin (i.e., viruses, bacteria, pheromones, natural plant compounds) in contrast to synthetic chemicals. Transgenic Bt cotton and corn are biopesticides because Bacillus thuringiensis (Bt) is a naturally occurring soil bacterium that has been genetically engineered into the plants.

Bio-security refers to the policies, and measures taken, for protecting a nation’s food supply and agricultural resources from both accidental contamination and deliberate attacks of "bio-terrorism." Now viewed as an emerging threat, bio-terrorism might include such acts as introducing pests intended to kill U.S. food crops; spreading a virulent disease among animal production facilities; and poisoning water, food, and blood supplies. The federal government is now increasing its efforts to improve bio-security because of the recognition that the United States is currently vulnerable, both from a civil and military standpoint.
Industry:Agriculture
The use of technology, based on living systems, to develop processes and products for commercial, scientific or other purposes. These include specific techniques of plant regeneration and gene manipulation and transfer. In the past, producers used cross-hybridization to alter a plant's genetic makeup. With biotechnology, DNA can be altered directly.

The November 1992 agreement between the United States and the European Union on export subsidy and domestic subsidy reduction commitments in the Uruguay Round of multilateral trade negotiations. The agreement also dealt with some bilateral agricultural trade issues.
Industry:Agriculture
Primarily used in the federal milk marketing order program. Represents the weighted average price of milk, per hundred pounds, paid to each farmer based on how Grade A (fluid grade) milk is allocated to different usage classes (e.g., fluid, manufacturing) by processors.
Industry:Agriculture
A federal export promotion program operated from 1983 to 1985 by the Foreign Agricultural Service. Federally guaranteed commercial loans at market interest rates (GSM-102) were combined (blended) with direct export credits (GSM-5) issued by the CCC at zero interest. This subsidized credit was made available to selected countries for a limited number of agricultural commodities. The program was terminated in 1985 when a federal judge determined that commodities shipped under blended credit were subject to cargo preference laws, which would have required that 50% of blended credit exports be shipped on higher-cost U.S. flag vessels.
Industry:Agriculture
In grain marketing, the combining of two different qualities of grain in order to change the total value of both lots. For example, it is common to blend grains of differing moisture or different foreign material content to achieve the requirements of a contract order.

Direct payments, under the definition of "production-limiting" measures as defined in Article 6 of the Uruguay Round Agreement on Agriculture, that are not subject to the commitment to reduce domestic support. To qualify for the exemption, payments must be based on fixed areas or yields, on a fixed number of livestock, or on 85% or less of the base level of production. See green box.
