In the field of food and agriculture, CEN develops European Standards that focus on food and feed safety. In particular, the technical committee CEN/TC 327 ‘Animal feeding stuffs - Methods of sampling and analysis’ develops methods of sampling and analysis for animal feeding stuffs, including chemical, biochemical, microbiological, physical and microscopical methods.
In a project steered by CEN, researchers from the National Food Institute at the Technical University of Denmark (DTU Food) developed EN 17374:2020 ‘Animal feeding stuffs: Methods of sampling and analysis - Determination of inorganic arsenic in animal feed by anion-exchange HPLC-ICP-MS’.
This new standard represents an analytical method for the determination of the content of inorganic arsenic in animal feed and feed materials. "This new standard will enable control laboratories to determine inorganic arsenic at relevant levels and will allow the establishment of future maximum levels for inorganic arsenic in feed and feed materials”, comments CEN/TC 327’s project leader Jens Sloth.
Inorganic arsenic, which occurs naturally in soil, water and certain foods, is carcinogenic to both animals and humans. Although EU feed legislation does not currently set maximum levels to limit its presence in feeding stuffs, competent authorities can request producers to demonstrate that the content of inorganic arsenic is lower than 2 mg/kg.
While previous methods measured the content of total arsenic in animal feed, i.e. both harmful inorganic arsenic as well as organic arsenic – which is considered to be far less problematic - this new standard method EN 17374:2020, published in July 2020, is able to detect inorganic arsenic at relevant levels.
