Olive Oil - Regulation

The International Olive Oil Council (IOOC) is an intergovernmental organization based in Madrid, Spain, with 23 member states. It promotes olive oil around the world by tracking production, defining quality standards, and monitoring authenticity. More than 85% of the world's olives are grown in IOOC member nations.

The United States is not a member of the IOOC, and the US Department of Agriculture does not legally recognize its classifications (such as extra-virgin olive oil). The USDA uses a different system, which it defined in 1948 before the IOOC existed. The California Olive Oil Council, a private trade group, is petitioning the USDA to adopt IOOC rules.

The IOOC officially governs 95% of international production and holds great influence over the rest. IOOC terminology is precise, but it can lead to confusion between the words that describe production and the words used on retail labels. Olive oil is classified by how it was produced, by its chemistry, and by its flavor. All production begins by transforming the olive fruit into olive paste. This paste is then malaxed to allow the microscopic oil droplets to concentrate. The oil is extracted by means of pressure (traditional method) or centrifugation (modern method). After extraction the remnant solid substance, called pomace, still contains a small quantity of oil.

According to an article by Tom Mueller in the August 13, 2007 Issue of the The New Yorker, regulation is extremely lax and corrupt. Meuller states that major Italian shippers routinely adulterate olive oil and that only about 40% of olive oil sold as "extra-virgin" actually meets requirements.
