In 2017 several 'minor' changes were made to the GLOBALG.A.P Version 5 standard. These changes included some minor musts becoming major musts.
 
From GLOBALG.A.P: 
The main reasons for issuing an update of the IFA Standard are amendments in the Compliance Criteria (CC) of sections 5.2.1 and 5.2.2 of the Crops Base module. In the first edition of V5.0 it was indicated that these Control Points (CP) will become Major Musts as of 1 July 2017. These two CPCC deal with the water management risk assessment and water management plan.
The Secretariat took this opportunity to include other changes that the relevant Technical Committees agreed upon. These include a level change of AF 16 (food fraud) and FV 5.7.3 (laboratory requirements for water testing). Both CPCC were changed to Minor Musts.
Clarifications were made to the Compliance Criteria of the Poultry module (PY 1.2, 5.2.2 and 8.2.5).
 
This update includes all changes, new master policy, facility and internal audit documents.
