Dear Colleagues,

We would like to thank the participants to the proficiency testing trial dedicated to the detection of staphylococcal enterotoxins (SE) types SEA to SEE (N° EILA / ANSES LSAL / CAT-BAC / 2013 / 03) for having taken the time to answer our satisfaction questionnaire sent on 23^th May 2014.

In fact, among 31 participants, 27 (87%) participated to this enquiry. Following the analysis of the replies, here is an overall view of the participants’ comments and our follow up:

Dear Colleagues,

As announced during the last workshop of the NRLs for Coagulase Positive Staphylococci (Maisons-Alfort, 04-06 June 2014), we are organising a training session on the confirmatory ELISA method (quantitative) for the identification and quantification of staphylococcal enterotoxins (types SEA to SEE) in food matrices.

This quantitative ELISA method will be also used in the aim of the certification of the future certified reference material (CRM) which will be organized by the IRMM-JRC.
