Summary Testing carried out in 2010 included the determination of 103 compounds in 19 commodities. Samples for testing were collected from production plants by inspectors of District Veterinary Inspections. 151 samples were tested, of which 67.5% were cereals grain, 29.1% processed cereals and 3.3% processed oil seeds. Validated analytical multiresidue methods were used to determine many compounds at the same time, in compliance with legally binding standards and tested during international proficiency tests (FAPAS – The Food Analysis Performance Assessment Scheme, EU – European Union). The following analytical techniques were used: GC/ECD/NPD and GC/MS. The positive results were confirmed in compliance with European Commission regulations. In 15 samples tested (9.9%), only in samples of processed cereals (25.0%) and cereals grain (3.9%), pesticide residues were found. Residues of chlorpyrifos, chlorpyrifos-methyl, cypermethrin, deltamethrin, fenpropimorph, malathion, pirimiphos-methyl, tebuconazole were detected. Residues were present mostly in samples of wheat bran (75.0%) and oat bran (25.0%), and samples of rye grain (33.3%). Maximum residue levels (MRLs) exceedances were not found. One case (0.7%) of unauthorized plant protection product use was stated.
