Our Certifications

We complemented our existing Quality Management System DIN EN ISO 9001 by Environmental Management System DIN EN ISO 14001. As a food producer we, of course, meet the European and German law requirements concerning food hygiene. Since 2004 we have established an HACCP-Concept, which has proven itself, as well as been integrated in certification of Management System for Food Safety DIN EN ISO 22000 since 2019.

We correspondingly oblige ourselves, to transparent handling of food and feed, at a continuously high level. These certifications are complemented by Kosher– and Bio-certificates. There already is a Halal-certification in place for selected products. Based on customers‘ request, we are open to further Halal-certifications.

In addition, we are registered at FDA (U.S. Food & Drug Administration) as an operating plant for food production (Product category 15: Food additives, GRAS or other ingredients that are used for processing).

Maximum transparency and complete retraceability of all products has proven itself, over the past decades, and is highly appreciated by our customers.

We are going to continuously follow that approach in the future!
