VLOG "Ohne Gentechnik" Standard

With the strong support of numerous stakeholders, the VLOG has developed a uniform "GMO-free" production and testing standard. This standard was designed together with representatives of producers of animal feed and food industry, certification bodies, interest groups and public representatives. It supports production facilities in the implementation of the legal requirements of "GMO-free" labeling and establishes uniform inspections for certification companies. The standard is available free as a download.

VLOG "Ohne Gentechnik" Standard

In July 2016 a new version (16.01) of the Standard was published, taking into account the practical experience of the previous months. Since 1 January 2014, the application of the Standard for obtaining a license for the use of the seal „Ohne GenTechnik " has been compulsory.

In addition to the Standard operating questionnaires, checklists, a sampling protocol and a GMO-free certificate are being provided. For certifications according to the VLOG „Ohne Gentechnik" Standard, the content of the VLOG operating questionnaires needs to be captured. However, own templates can be used. Even with the checklists, it is possible to use your own documents, however, the text of the control points must be copied 1:1. For all other attachments of the Standard it can be deviated from the documents made ​​available as long as the same content is transported only in another form.

To obtain a license to use the uniform „Ohne GenTechnik" seal, VLOG must be provided with prima facie evidence of the compliance with the criteria of the OG act (EGGenTDurchfG). Whether an external certification is required depends on the country where the production sites are located, the size of the complexity of the products to be labeled and the size of the risk of carryover of genetically modified ingredients. The criteria that make certification compulsory, can be found under chapter 2.1.1..

Certification bodies issuing certificates that are used as prima facie evidence for the VLOG have to enter into an agreement with the VLOG.

It is necessary to realize a contract (Certification Agreement for use of the VLOG Standard) between the standard body (VLOG) and the company that gets certified. The contract regulates the use of the VLOG-Standard. Once it is mutually signed, it will be presented by the company during the audit or sent to the appropriate certification body. Only after having done so a certificate can be issued.
