The U.S. Department of Agriculture has released its summary of the 2009 Pesticide Data Program.
The program samples food and water and analyzes the actual levels of pesticide residue, according to a news release.
In 2009, the U.S. Department of Agriculture and its Agricultural Marketing Survice conducted surveys on a variety of foods, including fresh and processed fruits and vegetables, beef, catfish, rice, groundwater, and treated and untreated drinking water.
Twelve states participated in the program in 2009: California, Colorado, Florida, Maryland, Michigan, Minnesota, Montana, New York, Ohio, Texas, Washington and Wisconsin.
The report has become controversial during the past few years as environmental groups, such as the Environmental Working Group, use the data to create "dirty dozen" lists of produce to avoid.
