Since 1875, quarantine laws have been enacted to protect domestic agriculture from foreign pests. Today, thanks to efficient agricultural production and swift commodity transport, California growers have access to widespread international markets. Domestic regulatory policies are no longer adequate and must yield to new and developing international regulatory policies. The General Agreement on Tariffs and Trade (GATT) is considering an initiative to harmonize plant quarantine regulations among nations. In addition, development of the “pest-free” zone concept has benefited both exporters and importers.
