Control according to plan
The residue monitoring is based on a product-specific control plan. In the case of wholesalers, the control plan defines the number of samples that are to be taken and tested during the course of the year. If you are a producer participating in the QS scheme, your coordinator organises independent sampling.
All test results are recorded in the QS database and evaluated by QS. To ensure that all requirements are met and that laboratory results can be compared, only QS-approved laboratories may be commissioned to perform the tests.
