EUPT AO-04 - Announcement

The Community Reference Laboratory for Pesticides in Food of Animal Origin and Commodities with High Fat Content in Freiburg, Germany, announces its fourth proficiency test (PT), thus enabling again each participating laboratory to assess its analytical capability by comparing its results with the assigned values.

A test material of butter fat will be supplied, spiked with up to 12 analytes from the list given in the announcement letter (mainly compounds belonging to the pesticide groups: organochlorines, organophosphates and pyrethroids). Approx. 30 g of the test sample will be supplied in March 2009. In addition, a blank (not spiked) portion of the same test material will be provided. Participating laboratories may use any analytical method. Four weeks after receiving the PT sample, results should be reported to the CRL. After receiving the results, a statistical evaluation of the data submitted will be performed and all quantitative laboratory results will be assessed by means of z-scores. Then, a report will be sent to the participating laboratories together with a certificate of participation.

The objectives of this survey are to assess the interlaboratory consistency of results from the analyses of pesticides in fatty samples and to provide a quality assurance assessment of the NRLs and the official laboratories within the EU.

Participation is mandatory for all laboratories selected as NRL for pesticides in food of animal origin and commodities with high fat content and, according to Art. 28 of EC Reg. 396/2005, for all official laboratories undertaking the analysis of these commodities for the official controls on pesticide residues. If participation is not possible, the Commission expects an explanation to be given by the laboratory. Laboratories are asked to return the fully completed registration form before February 6th, 2009, by e-mail to the CRL AO, even if they don't intend to participate. In the registration form, there is a possibility to explain the reason for non-participation.

The financial aid from the Commission covers the cooperation of the CRL with the NRLs of the EU Member States, only. Therefore, the participation of NRLs of EFTA- and Candidate States as well as of all official laboratories will be subject to a certain charge, due after re-ceipt of test material.

All documents relating to this Proficiency Test EUPT AO-04 including the detailed announcement letter and the registration form, are available on the restricted CIRCA area.
