History - 3-A Sanitary Standards Inc. Then and Now
The first standards for the hygienic design of equipment used in the dairy industry were introduced in the 1920s.  These standards became known as '3-A standards' for the three 'associations' or interest groups that cooperated to improve equipment design and sanitation - regulatory sanitarians, equipment fabricators, and processors.

Today, 3-A SSI is an independent corporation dedicated to education and the mission to promote food safety through hygienic equipment design in the rapidly changing food, beverage, and pharmaceutical industries.

How 3-A SSI operates:

The membership consists of four associations: American Dairy Products Institute, International Dairy Foods Association, Food Processing Suppliers Association and the International Association for Food Protection.
The Board of Directors consists of members designated by each association, plus a representative of the U.S. Department of Agriculture, the U.S. Food and Drug Administration, the Chair of the 3-A Steering Committee, and others.
The Chair of 3-A rotates among the three interest groups; the Chair serves a term of two years.
3-A SSI is supported by membership dues, sales from documents, 3-A Symbol license fees, and grants.
What 3-A SSI does:

Leads the development of standards for equipment and accepted practices for processing systems through a modern consensus process based on ANSI requirements.
