EUPT AO-06 Invitation letter

The European Union Reference Laboratory for Pesticides in Food of Animal Origin and Commodities with High Fat Content in Freiburg, Germany, announces its fifth 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 poultry will be supplied, spiked with analytes from the list given in the announcement letter (mainly compounds belonging to the pesticide groups: organochlorines, organophosphates and pyrethroids). Approx. 110 g of the test sample will be supplied in May 2011. 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 EURL. 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.

Time Schedule

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 register online via website from 28. February until 1. April 2011 even if they don't intend to participate. In the registration procedure, there is a possibility to explain the reason for non-participation.

There will be a general fee of 150 € for every participating laboratory (including NRLs) for shipping and handling. An invoice will be sent together with the samples.

All documents relating to this Proficiency Test EUPT AO-06 including the Final Report are available on the restricted CIRCA area.
