Over time, the structure of 3-A expanded to encompass a broader group of processors, equipment manufacturers and sanitarians in step with the changing structure of the industry. In 1944, the modern 3-A program was established through the formation of the Dairy Industry Committee, consisting of five national dairy processor groups and one supplier association: The American Butter Institute, American Dairy Products Institute, IAFIS, International Ice Cream Association, MIF, and the National Cheese Institute. It was also in 1944 that the U.S. Public Health Service committed to full cooperation with the 3-A program. The interests of dairy cooperatives were integrated into 3-A in 1996 with the Farm Industry Committee, established by the National Milk Producers Federation.
