1 Validation in food and feed microbiology: a unified approach set out by the Food Agencies or different approaches stimulated by the laboratories itself G. De Poorter, Director general Laboratories C. De Backer, National Reference Laboratory in food microbiology MicroVal Symposium, Amsterdam 20th of March 2007 Agence fédérale pour la Sécurité de la Chaîne alimentaire

2 2 Plan of the lecture Legislative context Analytical context Methods categories Available alternative methodologies Illustration Conclusion References

3 Agence fédérale pour la Sécurité de la Chaîne alimentaire3 Legislative context Commission Regulation (EC) n° 2073/2005 of 15 November 2005 on microbiological criteria for foodstuffs –Reference methods (mainly « ISO » standard methods) –Alternative validated methods Reference methods issued from the regulation Protocol set out in the standard ISO or internationally accepted similar protocols Third party

5 Agence fédérale pour la Sécurité de la Chaîne alimentaire5 Methods categories Standard methods Alternative validated methods Belgian official methods

6 Agence fédérale pour la Sécurité de la Chaîne alimentaire6 Methods categories - 2 Standardized methods –Characterized performances –Entire protocol, no simplification –French « routine » standard methods and some other standards : progressive abolition (until January 1, 2008) methodcategoryexamples standardinternationalISO, IDF EuropeanEN nationalNBN, NF, NEN, DIN, NMKL

7 Agence fédérale pour la Sécurité de la Chaîne alimentaire7 Methods categories - 3 Alternative validated methods –Commercial methods: simpler, faster and/or more economic than the reference methods –Standard ISO : 2003 « Protocol for the validation of the alternative methods» International recognition –FASFC considers that the alternative methods validated by AFAQ AFNOR Certification are in conformity with the provisions of article 5 of the Commission Regulation (EC) n° 2073/2005 –The alternative methods validated by other organizations or laboratories will be also recognized in Belgium if they fulfil the requirements of article 5 of the Commission Regulation (EC) n° 2073/2005 and if they provide at least the same guarantees as those described in the protocol of the standard ISO –Validation file to provide to FASFC and National Reference Laboratory in food microbiology for evaluation and possibly recognition

8 Agence fédérale pour la Sécurité de la Chaîne alimentaire8 Methods categories - 4 Belgian official methods –Worked out to meet a need –Written by the National Reference Laboratory in food microbiology and recognized by FASFC –Valid until January 1, 2008 for those where another reference method exists

13 Agence fédérale pour la Sécurité de la Chaîne alimentaire13 Conclusion List of the analytical methods recognised by FASFC for the food microbiological analyses in Belgium since about 11 years List strongly modified by the Commission Regulation (EC) n° 2073/2005 Reference methods and validated alternative methods Progressive disappearance of some standards and methods (cfr list of recognized methods) Obligation for private analytical controls to also align on Commission Regulation (EC) n° 2073/2005, before January 1, 2008 Imposition of specific methods for the analyses for FASFC from January 1, 2008 Alternative validated methods recognized by FASFC if they fulfil requirements of the Commission Regulation (EC) n° 2073/2005 and if they provide at least the same guarantees as those described in the protocol of the standard ISO Validation file to provide to FASFC for evaluation and possibly recognition List updated twice a year and available on the website of FASFC (www.afsca.be > secteur professionnel > administration des laboratoires > agrément > laboratoires agréés > notes de service)www.afsca.be Constant evolution, must anticipate changes
