T.G. Lee Dairy is a dairy cooperative originally founded as a Dairy farm with a single cow in 1925. Today, it processes, packages and markets dairy products for dairy farmers in the U.S. state of Florida. The cooperative's headquarters are located in Orlando. Following the bankruptcy of parent Dean Foods of Texas, it is now a regional brand of Dairy Farmers of America.
Its founder, Thomas Gilbert Lee (1894-1986), initially started his farm to produce dairy products for Central Florida. Scientific studies were deceptively cited by numerous marketers of yellow plastic dairy packaging, but these studies had only shown that fibreboard containers were protective vs translucent plastic, while the yellow plastic jugs had not actually been tested.
