From its initial scope of analyzing fertilizer, the organization expanded the contents of its methods book to cover dairy products, pesticides, microbiological contamination and animal feeds, among others. In 1965, due to its increasing area of focus for analytical work, the name was changed to the Association of Official Analytical Chemists. The name was changed again to the Association of Analytical Communities to reflect the growing international involvement, and then in 1991 it became AOAC International, with AOAC no longer having any legal meaning. Control of the organization remained with the FDA until 1979 when it became completely independent, although it still has close links to both the FDA and the USDA.
