EUPT AO BF1 Invitation Letter
The European Union Reference Laboratory for Pesticides in Food of Animal Origin and Commodities with High Fat Content (EURL AO) in Freiburg, Germany, invites all NRLs and OfLs to a special EUPT on infant formula matrix (milk based) proficiency test (PT). Participating laboratories have the possibility to assess its analytical capability by comparing its results with the assigned values.
A test material of infant formula powder will be supplied, spiked with relevant analytes from the list given in the announcement letter. There will be two target list with mandatory and voluntary pesticides on it.
Approx. 50 g of the test item will be supplied in mid August 2022. In contrast to former EUPTs a blank material of the same test item will be provided. Participating laboratories may use any analytical method. Four weeks after receiving the PT sample, results should be reported online to the EURL via the EUPT website. 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. A final report will be sent to the participating laboratories together with a certificate of participation.
A exemplary method for the determination of pesticides using GC- and LC-MSMS in infant formula used by EURL AO is available here (also please refer to EUPT AO 13). (Link to CIRCABC). (How to use CIRCABC)
The objectives of this EUPT are to assess the interlaboratory consistency of results from the analyses of pesticides in animal food 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 have this matrix in scope and, according to Art. 101 of Reg. (EU) 625/2017 and Art. 28 of EC Reg. 396/2005, for all official laboratories undertaking the analysis of these commodities (baby food, infant formula) for the official controls on pesticide residues. If participation is not possible, the Commission expects an explanation to be given by the laboratory. In the EU Lab-Netwok database the status of each laboratory is stored. It can be cheked during registration, if your laboratoory is obliged to participate or not.
Laboratories are asked to register online via registration website from 23 May - 20 June 2022 even if they don't intend to participate. In the registration procedure, there is a possibility to explain the reason for non-participation.
After registration the participants will receive their username and password for EUPT AO BF1. Therefore, participants will be able to re-enter the database and change/update the entries (e.g. addresses for shipment and invoice, contact data). Deadline for these changes is 01 August 2022.
Before the shipment of the samples participating laboratories have to select the analytes from the target list being part of their analytical scope. Deadline for any changes in scope will be one day before the shipment of samples (12 August 2022).
There will be a general fee of 180 € for every participating laboratory from EU and EFTA countries (including NRLs) and 360 € for third countries for shipping and handling. The organizers will not accept participants from Third Countries if they cannot guarantee that the test items will arrive in the laboratories in good conditions (duration of shipping > 3 days). An invoice will be sent together with the samples.
All documents relating to this Proficiency Test EUPT AO-BF1 are available in the restricted area (CIRCA BC).
