Brief description

The VLOG standard sets out the general requirements for certification of GMO-free products and for use of the “Ohne GenTechnik” (no genetic engineering) seal. It is a private certification standard managed by the non- profit organization VLOG, which is based in Germany.

Detailed description

Certification and use of the “Ohne GenTechnik” (no genetic engineering) seal can be applied by businesses if they produce nutritional products without using genetic engineering procedures or genetically modified organisms (GMOs).

The standard can be applied to products such as meat, milk, eggs, honey, cereals, fruit and vegetables, in primary production (e.g. dairy farms), to food production and processing, and to logistics services (e.g. transport of milk) and feed production.

A food product bearing the “Ohne Gentechnik” seal must meet the following criteria:

  • It should contain no genetically modified organisms (GMOs) or parts thereof.
  • It should contain no vitamins, aromas, enzymes and other food additives manufactured with the help of GMOs.
  • It should contain no GMO material in animal feed, with strict time limits being observed if animals have at some point been reared on feed containing GMOs.
