Indiana was late to join the organic food movement, which arose in the 1960s in response to modern chemical farming, but the state is starting to make up lost ground, said Cissy Bowman, executive director of Indiana Certified Organic, LLC.

As the state's only government-approved organic certifier, she has given the stamp of approval to more than 50 Hoosier organic farms and expects that to double this year.

Herself an organic farmer, Bowman said the organic market has undergone incredible growth since she began raising organic vegetables 20 years ago on six acres near the Hendricks County town of Clayton.

"Any food you can think of, you can buy an organic version now. It's not just that bag of whole wheat flour on the store shelf anymore," she said.

Traders Point Creamery delivers to about 70 area stores, with weekly shipments to Chicago-area stores, but demand often outpaces supply, particularly during the winter and summer.

"The cows can't keep up. We sell pretty much everything we produce," said David Robb, the creamery's manager of business development.

Cathy Greene, an agricultural economist with the U.S. Department of Agriculture's Economic Research Service, said the retail market for organic foods continues to grow about 20 percent each year.
