In 2014 it was decided to phase out the standard GMP+ B6 Cultivation of feed materials.
As from 1-1-2018, certificates based on the GMP+ B6 standard are not valid anymore. For buying feed materials directly from primary company “ANNEX 4: Gatekeeper protocol for purchase of unprocessed agricultural products from the grower / grower-collector” of GMP+ BA10 must be used.
The standard can only be consulted from 01-01-2018 via the page History.
