An Organic Certification is given by National Organic Program (NOP) which is an USDA accredited agent. Each of these certifying agents is authorized to issue an Organic Certificate to operations that comply with the USDA organic regulations. The NOP is a regulatory program housed within the USDA Agricultural Marketing Service. They are responsible for developing national standards for organically-produced agricultural products. The standards assure consumers that products with the USDA organic seal meet consistent, uniform standards.
