GM labelling approaches
How various countries are marking GM
Mandatory or voluntary approach: While the EU, Australia, New Zealand, Brazil, South Korea and a few other countries have adopted mandatory labelling, USA and Canada permits voluntary labelling. Some permit voluntary GM-free labelling. Thresholds set for labelling exemption: Thresholds are based on quantity of GM DNA or weight of GM ingredient in the total product. Japan has adopted a limit of 5 per cent of GM ingredients (by weight) in the product, whereas the EU provides a limit of 0.9 per cent GM DNA per ingredient in view of adventitious or technically unavoidable presence, which the producer has to prove.
