GMP+ Certificate

GMP stands for voor Good Manufacturing Practices. In 1992 the current GMP+ Feed Certification scheme started out with this. Afterwards, it developed into a full-fledged certification scheme by integrating ISO quality management requirements, HACCP and other elements. The + stands for the integration of HACCP: ‘Hazards Analysis and Critical Control Points’. The foundation of the GMP+ systematic is partly determined by continuous improvement according to the principle of the Deming circle ‘Plan, Do, Check, Act’: write down what I’m doing, do what I’ve written down and providing proof that I effectively did it.
