This study addresses a new issue in the commercialisation of GM crops, namely the occurrence of traces ¿ or "low-level presence" (LLP) ¿ of nationally unapproved GM material in crop imports. The commercialisation of GM crops is a regulated activity and countries have different authorisation procedures. Hence new GM crops are not approved simultaneously. This "asynchronous approval" (AA), in combination with a "zero tolerance" policy to¬wards LLP, is of growing con¬cern for its potential economic impact on international trade. To forecast the future evolution of this issue, we compiled a global pipeline of GM crops that may be commercialised by 2015. This pipeline is analysed by crop and likely LLP scenarios are discussed. While currently there are around 30 commercial GM crops with different transgenic "events" worldwide, it is expected that by 2015 there will be over 120. Given that already with 30 events problems of LLP have occurred, these issues are likely to intensify when more events become available in more countries.
