The purpose of organic certification is to answer the question “How do I know this is organic?”
First-party certification means a farmer offers their personal assurance that a product is organic. If the farmer is a relation, a neighbor, or someone you know well, you might be satisfied with first-party certification.
Second-party certification means that the farmer belongs to an organization, and that organization provides assurance that the product is organic.
Third-party certification means that an independent inspector from an accredited certifying agency visits the farm and verifies that the farmer is following organic practices.
