In the QS scheme, approved laboratories regularly inspect the compliance of the participating businesses with QS requirements within the framework of various monitoring programmes. The experience and responsibility of laboratory personnel play a key role in this process. They test the submitted samples for environmental toxins, residues of plant protection products, mycotoxins or heavy metals as well as for hygiene parameters like salmonella contamination.
QS-approved laboratories continuously prove that they are in a position to sustainably provide their services in line with consistently high standards by regularly participating in laboratory performance assessments organised by QS as well as external round robin tests.
