“…Pesticide residues determination in food commodities, though carried out in a good number of occasions, has a high interest . On the one hand, it is important to suitably control the presence of pesticides in food samples (especially to guarantee food safety), to check the presence and persistence of recently authorized pesticides and to find out if illegal practices are being developed .…”

The AOAC 2007.1 quick, easy, cheap, effective, rugged, and safe official method, together with gas chromatography coupled to a triple quadrupole mass spectrometer was applied for the analysis of 38 multiclass pesticides from dried fruits typically cultivated and exported from Colombia: uchuva (Physalis peruviana), lulo (Solanum quitoense), guanabana (Anona muricata), and pitahaya (Hylocereus undatus). The whole method was validated in terms of matrix‐matched calibration, matrix effect, and recovery using atrazine‐d5 as internal standard, triphenylphosphate for quality control of the injection, and a proper mixture of analytes protectants. Matrix‐matched calibration data were found satisfactory for all pesticides and dried fruits, reporting R2 values above 0.99. Matrix effect values evidenced the existence of such effect in most cases. The applied procedure gave satisfactory recovery percentages (70–120%) and relative standard deviation values (< 20%) for 92% of the 456 combinations pesticide/fruit studied (spiked levels of 25, 200, and 400 µg/kg). Finally, 20 real dried fruit samples were analyzed and residues of tebuconazole were found in two samples of uchuva at a concentration below the lowest calibration level of the method for one of them and at 10.8 ± 1.6 µg/kg for the other, being below or similar to the general maximum residue level established for monitoring purposes in food applications.

“…Moreover, meat could convey and concentrate exogenous pollutants and their metabolites, while processed meat may exhibit reduced concentration of some substances and creation of new toxic ones (Püssa, ; Chen et al , ; Zacs et al , ). Many pesticides revealed a lipophilic nature with the consequent risk that foods rich in fat could represent a potential vehicle of these contaminants for animals and humans (Madej et al , ). Therefore, the evaluation of fipronil in meat and meat products is fundamental, also due to the European and Italian alerts and the introduction of the analysis of fipronil in the Italian Residual Plan 2018, as a consequence of the non‐conformities found in the 2017 and first half of 2018.…”

The aim of this study was to validate the method for detection and quantification of fipronil and fipronil sulphone in meat products and study the effects of these pollutants on meat nutritional quality. The determination coefficients (R2) of the analytes were 0.999, while intra‐laboratory CV% for repeatability and reproducibility ranged from 0.83% to 19.19%. Meat nutritional quality was assessed before and after the addition of analytes in meat samples. Both total and essential amino acids in meat decreased (P < 0.001) with increasing levels of added analytes, suggesting their detrimental effect on meat amino acid composition. The amino acid composition of meat did not show an univocal behaviour as consequence of fipronil and fipronil sulphone addition. In particular, aspartate, glutamate, arginine (P < 0.05), threonine, alanine, lysine and proline (P < 0.001) showed a significant decrease with increasing levels of added analytes, while serine (P < 0.001) evidenced an opposite trend.

Apple peel is frequently exposed to pesticides, especially in the last stages of the pesticide treatment practice. For a certain period, peel retains most of the applied pesticides, which precisely indicates the presence of pesticide residues. This study was conducted to establish and evaluate the method for the residue analysis of pyrimethanil, cyprodinil, trifloxystrobin, bifenthrin and boscalid by GC–MS in peel of Granny Smith, Golden Delicious and Idared varieties. The method consisted of few steps, without the routine usage of sorbents, and resulted in efficient removal of waxes, targeted as main interferences in GC–MS analysis. The matrix effect, boscalid selectivity issue, trend of lower trueness for bifenthrin in all matrices and for all analytes in Granny Smith matrix were in some way associated with the waxes. Finally, the method was applied to the analysis of three varieties of apple orchard samples, after 9 and 5 months of treatment with commercial formulations that contain pyrimethanil, cyprodinil and boscalid as active ingredients. Since the developed method consisted of few steps and used nontoxic and economic reagents, it could be implemented as a fast, economic and reliable screening method.
