The standardization of methods for the detection and determination of additives, residues and contaminants in food is the objective of CEN/TC 275. Beside, CEN/TC 327 works on the elaboration of standardized test methods for the analysis for animal feeding stuffs. Animal feeding stuffs are defined as any substance or product, including additives, whether processed, partially processed or unprocessed, intended to be used for oral feeding to animals. The following standards related to the determination of inorganic arsenic have been published so far by CEN/TC 275 and CEN TC/327:

-          EN 15517:2008 Foodstuffs - Determination of trace elements - Determination of inorganic arsenic in seaweed by hydride generation atomic absorption spectrometry (HGAAS) after acid extraction

-          EN 16278:2012 Animal feeding stuffs. Determination of inorganic arsenic by hydride generation atomic absorption spectrometry (HG-AAS) after microwave extraction and separation by solid phase extraction (SPE)


For the determination of inorganic arsenic, the following stardards are being elaborated :

-          CEN/TC 275 WI 00275238 Foodstuffs - Determination of elements and their chemical species - Determination of inorganic arsenic in foodstuffs of marine and plant origin by anion-exchange HPLC-ICPMS following waterbath extraction (expected to be published 2015-2016)

-          CEN/TC 327 a similar work item has started up in May 2013


Standard methods for arsenic speciation analysis have been developed, validated and approved by US Food and Drug administartion :

-          FDA: Elemental Analysis Manual: Section 4.10: HPLC-ICP-MS Determination of Four Arsenic Species in Fruit Juice [7-[file:///Y:/Unit_MANT/Algemeen/Research%20Programme/EU/FP7/2_Running%20Projects/FP7-KBBE-2011-2.4.02-TDS_EXPOSURE/03_Project/WP5/Task%205.4.2%20-X-%20Choice%20of%20adequate%20analytical%20methods/7.%09http:/ Link]].


Supplementary information can be found at the European Union Reference Laboratory for Heavy Metals in Feed and Food (EURL-HM)[8-[file:///Y:/Unit_MANT/Algemeen/Research%20Programme/EU/FP7/2_Running%20Projects/FP7-KBBE-2011-2.4.02-TDS_EXPOSURE/03_Project/WP5/Task%205.4.2%20-X-%20Choice%20of%20adequate%20analytical%20methods/8.%09http:/ Link]]. The task of the EURL-HM in Feed and Food is to facilitate the implementation of Regulation (EC) No 1881/2006 and Directive 2001/22/EC establishing the maximum levels of heavy metals such as lead, mercury and cadmium in different foods. One of the core tasks of the EU-RLs is to organise interlaboratory comparisons where the appointed national reference laboratories can participate. The three types of matrices covered by the EU-RLs are: wild caught fish, food of plant origin and animal feed.
