An organic seal is a quality and test seal with which products from organic farming are marked. In 2010, a binding new organic seal was introduced throughout the EU, also known as the EU organic logo, which identifies food from organic farming (a star-shaped leaf on a green background). 

This seal replaced the German state organic seal (green hexagon with "BIO" lettering), which had existed since 2001, with the same standards in terms of content. Due to the high degree of popularity of its predecessor, both seals are still often used today.

The use of this certification is strictly regulated by the publisher and is subject to ecological requirements. Compliance with the criteria by producers is ensured by a documentation obligation as well as regular sampling and examination of product samples. Compliance with the regulations is monitored in Europe by the responsible Eco-Control bodies.

Foods labelled with the organic seal must, among other things:
•    Not be produced by or with/from genetically modified organisms
•    Not to be produced with the use of synthetic pesticides
•    Contain no more than 5% conventionally produced components (in exceptional cases, if ingredients are not available in ecological quality, in accordance with Annex VO)
•    not contain sweeteners and stabilisers as well as synthetic colourants, preservatives and flavour enhancers
•    not result from monotonous crop rotations (two-, three- and four-field farming) 
•    and much more: more information on the EU Organic Label
