Pesticides in raw milk
Parameters (qualitative): identification of various pesticides
Parameters (quantitative): quantification of the identified pesticides [mg/kg]
Article Number: 2011117
Description: This is a multi-residue proficiency test. For the PT on pesticides, a pre-selection of pesticides was made according to relevance: listed in the list of analytes published by the DRRR. This is available via the DRRR homepage: https://drrr.de/en/proficiency-testing/food-and-feed/ From this list, a selection of pesticides will be available for identification and quantification in the PT round.

Description: Many per- and polyfluorinated substances (PFAS) are subject to various restrictions in the European Union. For example, PFOS, PFOA, PFNA and PFHxS are subject to the maximum levels in selected foods introduced in the Contaminants Regulation (EU) 2023/915. Commission Recommendation (EU) 2022/1431 also recommends monitoring the presence of other PFAS in food, including PFDA, PFBS and PFOSA. This proficiency testing offers you the opportunity to check your analyses of a large number of PFAS.
