Topco Associates LLC is the largest American retail food GPO (Group Purchasing Organization) and the sixth largest private company in Illinois.

[1][2] On September 28, 1944, to deal with wartime shortages, a small cooperative named Food Cooperatives, Inc., was formed by a group of Wisconsin food retailers to supply its members with private label dairy products and paper goods.

The products procured by this organization were sold under the Food Club and Elna labels.

This was the beginning of Topco Associates, Inc. Topco established its first fresh produce division in 1958, its first health and beauty and not-for-resale programs in 1960, and began exploring fresh beef opportunities in 1967.

Topco purchased competitor Western Family Foods in June 2016.
