Abstract: The EU is a major importer of protein rich feedstuffs as soy, which is increasingly produced with GM varieties.Only GM varieties approved in a lengthy approval procedure can be imported to the EU.The EU zero tolerance policy for unapproved GM means that only soy batches without traces of EU-unapproved GM varieties can be imported.Relaxing the zero tolerance policy for unapproved GM-soy varieties to an alternative tolerance threshold might prevent the import decline and consequential problems.This study evaluates alternative tolerance thresholds for EU-unapproved GM soy in combination with alternative delay periods of EU approval for use in feed compared to approval for production in soy exporting countries by using a stochastic computer based model of a three segment supply chain of soy producers in the USA, Brazil and Argentina, EU importers and feed producers.Results show that a two year delay period can lead to problems for the supply of soy to EU.This conclusion is not influenced by the chosen tolerance threshold level within the range 0.0-0.9%.When both Brazil and the EU have the same approval policy, supply problems are not expected.
