It's simple. Food grown and labeled organic must have all production practices from the field through the finished product inspected annually by a third party certification organization.
This certification ensures that:
1) No chemical fertilizer, pesticides or herbicides have been used on the fields and pastures for a
minimum of three years.
2) The farmer and processor have annual certification inspections of their operations.
3) Detailed records of farming and processing practices have been kept to ensure compliance.
4) Only ecologically friendly methods and substances have been used to make a particular product.
Be sure to look for the certification seal on products labeled "organic" .
