The certification body shall control the structural requirements in the context of the initial authorisation procedure.
Control procedures relating to the flow of goods, traceability and processing requirements shall take place at least every two years for each processing and refining undertaking, or every four years in the case of summer pasture holdings. For production undertakings, such procedures shall be carried out on the basis of a statistically representative random sample.
In the case of the Protected Geographical Indications (PGIs), testing of the final product shall be carried out once annually on the basis of a statistically representative sample of undertakings. In the case of Protected Designations of Origin (PDOs), these tests will take place at least once per year in every production, processing or refining undertaking which markets the final product. Where an undertaking markets the production of several operators, testing of the final product should be performed on a random sample of lots of each operator.
Undertakings where irregularities are found are subject to retesting on a systematic basis.
