Whenever there's real value around, someone will come up with a counterfeit. For example, my farm is certified organic by the state of New Hampshire. The inspector came to visit us just last week, toured our place, asked detailed questions about our soil-improvement plan, and made sure our fields haven't been touched by a chemical fertilizer or pesticide within the last three years.
Some states have strict rules and regular inspections.
Some don't have any at all. So growers who ship and stores that buy across state lines are pressing for uniform national organic standards. The Department of Agriculture is drawing up those standards now and running into one huge area of disagreement. Most organic growers would never use gene-spliced crops. Bt is a natural killer of Colorado potato beetles.
