4.      Separation:分離
ü       Some processors produce only organic, but most do both: organic and conventional.一些加工者只加工有機的，但是大多數有機和常規都加工。
ü       These latter handlers have to set up a good system for separating organic products from con­ventional ones: from the moment of reception of the raw material, through all steps of processing, storage rooms, etc., until sale. Separation must also be safeguarded between organic and transi­tional products, or products certified according to different standards (e.g. NOP / EU).后者應建立一個很好的將有機產品與常規分離的體系：只收到原料時起，到所有加工步驟，倉庫等指導銷售。還必須保證有機和過渡期產品，根據不同的標準(如：NOP / EU)認證的產品的分離。
ü       The best separation, of course, is in space: have separate warehouses and processing lines for or­ganic.最好的分離當然是空間上的：有機具有分開的倉庫和加工線。
ü       However, this may often not be possible; in this case, you can separate in time: you proc­ess or­ganic at different times on the same line as conventional; before processing organic, you have to clean the line.然而，有時候是不可能的，在這種情況下，你可以在時間上進行分離：在不同時間相同的生產線上加工有機和常規產品；加工有機之前，應清洗生產線。
