Conventional products, i.e. those produced without genetic modification, can be contaminated unintentionally by GMOs during harvesting, storage, transport or processing. However, conventional products "contaminated" in this way will not be subject to traceability or labelling requirements if they contain GMO traces below a 0.9% threshold level, provided the presence of GM material is adventitious or technically unavoidable. This is the case where farmers can show the competent authorities that they have taken appropriate measures to avoid the presence of GM material.
