Test Description

As the need for greater yields in agriculture grows as the world population grows, so does the risk that foods we consume may carry residues of those pesticides if they are not used correctly. Absorbption of pesticides from the soil or through the aerial growth means that any part of the plant may be contaminated, including the seeds. Furthermore pesticides may be used to treat the dried seeds during storage, again leading to contamination at the point of consumption. In a study carried out in 2019 in Turkey, 9 out of 12 samples of pumpkin seeds contained measurable levels of pesticide residues. All 9 contained a banned pesticide and 3 also contained imidacloprid at levels above the MRL. 2 others also contained chlorpyriphos residue.

The Fapas pesticide residues proficiency tests are based on the EU monitoring list and associated MRLs but are widely applicable to most geographic areas. We also base our statistical data analysis in keeping with quality assurance guidelines as laid out in EC SANTE/11945/2015. This proficiency test requires identification and quantification of the analytes.

Proficiency testing activities can be used as part of a wider quality assurance programmes. Through benchmarking your current routine analysis ability, areas for improvement can be highlighted, from which to achieve high quality, credible test results for your customers.
