3-A Sanitary Standards, Inc. (SSI) is a not-for-profit organization that creates hygienic design and fabrication standards for manufacturing equipment used in the food and beverage and pharmaceutical industries. It consists of three groups of volunteers: government organizations; food, beverage, and pharmaceutical manufacturing companies; and food, beverage, and pharmaceutical equipment manufacturers. Representatives from each of these three groups come together—typically on a monthly basis—to discuss maintaining and updating specific standards.
