Proficiency Test: Aflatoxin B1 in two naturally contaminated coconut samples
The European Union Reference Laboratory for Mycotoxins organises a proficiency test on the determination of Aflatoxin B1 in coconut (copra).
The objective of this study is to evaluate the measurement capabilities of European National Reference Laboratories (NRLs) and Official Food Control Laboratories (OCLs) for this target analyte.
Test material and analytes
The test material is naturally contaminated coconut powder (not defatted)
Participants will receive two different test samples to report. In addition an aflatoxin B1 free sample will be send too which may be used to determine the recovery of the analysis. Laboratories will be asked to report the recovery corrected value (µg/kg), including the recovery (%) and measurement uncertainty (µg/kg) for a coverage factor of 2 (k=2).
The performance of the participants will be rated by z-scores and zeta-scores.
Participation in EURL PTs is for official control laboratories only in line with Regulation 882/2004. Therefore only NRLs for Mycotoxins and OCLs (indicated by their NRL) may participate.
