The logo will soon appear on food packages across the EU
A new EU-wide "Euro-leaf" logo will be compulsory from 1 July for all pre-packaged organic food produced in any of the 27 EU member states.
The green logo, featuring the 12 EU stars in the shape of a leaf, will be optional for imported produce.
Existing national logos for organic food will be allowed to appear next to the new EU logo.
A German student won a competition to design the new symbol. Dusan Milenkovic got a prize of 6,000 euros (£5,254).
Some 130,000 people voted online to choose the symbol and Mr Milenkovic's entry got 63% of the overall vote. The competition was organised by the European Commission.
