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 cadmium have been published so far by CEN/TC 275 and CEN/TC 327:

-          EN 13805:2002 Foodstuffs - Determination of trace elements - Pressure digestion

-          EN 14082:2003 Foodstuffs - Determination of trace elements - Determination of lead, cadmium, zinc, copper, iron and chromium by atomic absorption spectrometry (AAS) after dry ashing

-          EN 14083:2003 Foodstuffs - Determination of trace elements - Determination of lead, cadmium, chromium and molybdenum by graphite furnace atomic absorption spectrometry (GFAAS) after pressure digestion

-          EN 14084:2003 Foodstuffs - Determination of trace elements - Determination of lead, cadmium, zinc, copper and iron by atomic absorption spectrometry (AAS) after microwave digestion

-          EN 15763:2009 Foodstuffs - Determination of trace elements - Determination of arsenic, cadmium, mercury and lead in foodstuffs by inductively coupled plasma mass spectrometry (ICP-MS) after pressure digestion

-          EN 15510:2007 Animal feeding stuffs - Determination of calcium, sodium, phosphorus, magnesium, potassium, iron, zinc, copper, manganese, cobalt, molybdenum, arsenic, lead and cadmium by ICP-AES

-          EN 15550:2007 Animal feeding stuffs - Determination of cadmium and lead by graphite furnace atomic absorption spectrometry (GF-AAS) after pressure digestion

 

For the determination of cadmium, the following stardards are being elaborated :

-          WI 00275271 prEN 13805 Foodstuffs - Determination of trace elements - Pressure digestion

 

Standard methods for the determination of cadmium have been developed, validated and approved by US Food and Drug administartion :

Supplementary information can be found at the European Union Reference Laboratory for Heavy Metals in Feed and Food (EURL-HM)[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:/irmm.jrc.ec.europa.eu/EURLs/EURL_heavy_metals/Pages/index.aspx) 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.
