To avoid trade barriers, NAFTA encourages countries to apply relevant international standards in the development of their SPS measures, if necessary. However, each country is allowed to adopt a higher standard than international standards in order to achieve an appropriate level of protection of human, animal or plant health, if the standard is based on scientific principles. NAFTA signatories agreed to work on „equivalent“ SPS measures without reducing the desired and appropriate national level of protection. Equivalence recognizes that different methods can be used to achieve the same level of protection. Each country has agreed to accept the SPS measures of other countries as equivalent, provided that the exporter proves that the SPS measures are in line with the level of protection desired by the importer as long as it is based on risk assessment techniques (Looney, 1995). The North Atlantic Free Trade Agreement was signed in 1994 and covers the United States, Canada and Mexico. It is a treaty that aims to ensure the mutual economic prosperity of the three nations by removing trade restrictions. In addition, in accordance with Article III of the Washington Agreement, BECC has a board of directors, a director general, an assistant director general, an advisory board, and all other officials and agents in the border area to carry out the tasks that BECC can define. The North American Free Trade Agreement (NAFTA) between Mexico, the United States and Canada has had a profound impact on Mexican regulation. Therefore, even though it is not a Latin American agreement, it remains extremely important for the region. NAFTA contains a text on health and plant health measures, modelled on the Uruguay Round agreement on health and plant health measures.

Section 756 of NAFTA recommends that the three countries „seek the equivalence of their health and plant health standards.“ This article was written to avoid commercial disputes between the three food products traded. The idea is that countries commit to harmonizing food production processes „as much as possible“ and that the measures do not become disguised trade restrictions. The European Union has acquired supranational status because of the power vested in it by its Member States, which takes over the powers of its states. For example, the European Union has its own currency and has mandated trade agreements. The other organisations listed do not have the same power as the European Union. The North Atlantic Free Trade Agreement (NAFTA) was signed in 1994 between Canada, the United States and Mexico. The primary objective of the treaty was to remove barriers to trade between the three countries and to offer reciprocal benefits to stimulate growth. However, it is economic globalization, and in particular the liberalization of world trade in agricultural raw materials, that has become a priority for rural events, both in the North and in the South.
