Update on IRMM-359 CRM for staphylococcal enterotoxins

We are pleased to transmit you an update from EC/JRC regarding the 3 Certified Reference Materials (CRMs) on SEA in cheese powder (IRMM-359a-c).

Their certificates have now been updated with ELISA-based quantitative values derived from a collaboration with our laboratory, in particular. These values have been included in the section "additional material information" of the certificates. A short reference to this work was added to the certification report (addendum in page 5).

Please see: https://crm.jrc.ec.europa.eu/p/q/359/IRMM-359-CHEESE-POWDER-SEA/IRMM-359

This information is important for the ones of you using these CRMs as well as for the national networks you coordinate.
