"Purity of Federal 'Organic' Label Is Questioned"

"Relaxation of the federal standards, and an explosion of consumer demand, have helped push the organics market into a $23 billion-a-year business, the fastest growing segment of the food industry. Half of the country's adults say they buy organic food often or sometimes, according to a survey last year by the Harvard School of Public Health.

But the USDA program's shortcomings mean that consumers, who at times must pay twice as much for organic products, are not always getting what they expect: foods without pesticides and other chemicals, produced in a way that is gentle to the environment."
