All organic farms are inspected by bio.inspecta from Frick, Switzerland according to BioSuisse Knospe standards. Since 1999, bio.inspecta has also performed certification. This means that the same officially accredited organisation performs inspection and certification in Liechtenstein as well as for Knospe farms in Switzerland. The association numbered more than 30 members by the end of 1999. The association supports the production, processing, trade and consumption of organic products from Liechtenstein.
