# Commission Regulation (EC) No 401/2006 of 23 February 2006 laying down the methods of sampling and analysis for the official control of the levels of mycotoxins in foodstuffs (Text with EEA relevance), Division 4.3.2.8: Validation report

Extent: E+W+S+N.I.

The validation report shall contain:
A statement on the STC
A statement on the obtained cut-off.
A statement on calculated false suspected rate
A statement on how the false suspected rate was generated.
Table A
Commodity groups for the validation of screening methods
If a buffer is used to stabilise the pH changes in the extraction step, then this commodity group can be merged into one commodity group ‘ High water content ’ .
‘ Difficult or unique commodities ’ should only be fully validated if they are frequently analysed. If they are only analysed occasionally, validation may be reduced to just checking the reporting levels using spiked blank extracts.
