Residue and feed monitoring: How is subcontracting regulated?
The entry form for laboratories indicates the methods/parameters that a laboratory can subcontract to another laboratory with QS recognition. Subcontracts can only be issued to laboratories that themselves have a QS-recognition for the inspection of the corresponding inspection method/parameter. An inspection method/parameter can only be assigned to one laboratory in a subcontract. Subcontracting must be approved by QS.
