U.S. sales of organic products (food and non-food) reached $24.6 billion by the end of 2008, growing 17% over the previous year, despite tough economic conditions, according to the Organic Trade Association (OTA).

The Greenfield, MA-based group’s 2009 Organic Industry Survey, indicates that while the overall economy has been losing ground, sales of organic products reflect very strong growth during for 2008.

“Organic products represent value to consumers, who have shown continued resilience in seeking out these products,” said Christine Bushway, OTA’s executive director.

The survey, conducted by Lieberman Research Group on behalf of OTA, measured the growth of U.S. sales of organic foods and beverages as well as non-food categories such as organic fibers, personal care products and pet foods during 2008. Results show organic food sales grew in 2008 by nearly 16% to reach $22.9 billion, while organic non-food sales grew 39% to reach $1.6 billion. As a result, organic food sales now account for approximately 3.5% of all food product sales in the U.S.

“This marks another milestone for the organic food market,” said Bushway.

With tough economic times, consumers have used various strategies in continuing to buy organic products. Because most venues now offer organic products, consumers have the opportunity to shop around. Increased use of coupons, the proliferation of private label brands, and value-positioned products offered by major organic brands all have contributed to increased sales, according to OTA.
