Ensuring measurement quality in aflatoxin analysis: new certified reference material released

0

JRC-IRMM has released a certified reference material for mycotoxin analysis, namely aflatoxins in compound feedingstuff (ERM-BE375), intended for method validation purposes and for performance control.

Aflatoxins are naturally occurring contaminants in food and feed of plant origin, produced by various fungal species. They are potent liver carcinogens and are therefore classified as carcinogenic to humans by the International Agency for Research on Cancer. Commission Regulation (EC) No 1881/2006 defines maximum levels for aflatoxins in food and Directive (EC) No 32/2002 for animal feed. The certified value for aflatoxin B1 in ERM-BC375 is close to the regulatory limits set in European Directive (EC) No 32/2002.

In order to resemble as real a sample as possible, the material was produced with naturally incurred raw material, i.e. the production process neither comprised a spiking nor a removal step. The certified values are based on an interlaboratory characterisation study. The uncertainties of the certified values include contributions from the characterisation study and from homogeneity and stability assessments. Preparation and certification of ERM-BE375 is described in detail in the certification report. The material can be ordered from the online catalogue.

The materials have been produced according to ISO Guides 34 and 35.
