“…For making a fair decision on the compliance of a sampled lot with the relevant MRLs, the uncertainty of measured residues should always be considered as per ISO Standard 17025 [32]. The practical application of the principles is explained in detail by Ambrus et al [34].…”

“…Consequently, the likely upper 95-98% tail of the distribution of the residues in repeated composite samples should be predicted and compared to the MRL of the importing county to make sure that the exported lot will be accepted. Therefore, for preexport control the sampling uncertainty should also be accounted for in the combined uncertainty of the whole determination process (CV R ) [34,37]. For this reason, an action limit (AL) lower than the MRL should be used as the acceptance criterion.…”

“…For the evaluation of the test results the measurement uncertainty should always be considered according to ISO Standard 17025 and Codex GL [32,33]. Where the compliance of locally marketed products is tested, the combined relative uncertainty of the within laboratory reproducibility (CV L ) [34] or the 0.25 default value introduced by the EU [35] should be used. For the control of imported products, specific import MRLs apply, if available.…”

As mandated by the EU and the national risk management duties, pesticide residues were determined by four specialized laboratories in 9924 samples taken from 119 crops of economic importance in Hungary and imported foodstuffs during 2017–2021. The screening method applied covered 622 pesticide residues as defined for enforcement purposes. The limit of detection ranged between 0.002 and 0.008 mg/kg. The 1.0% violation rate concerning all commodities was lower than in the European Union. No residue was detectable in 45.9% of the samples. For detailed analyses, six commodities (apple, cherry, grape, nectarine/peach, sweet peppers, and strawberry) were selected as they were analyzed in over 195 samples and most frequently contained residues. Besides testing their conformity with national MRLs, applying 0.3 MRL action limits for pre-export control, we found that 73% of the sampled lots would be compliant with ≥90% probability based on a second independent sampling. Multiple residues (2–23) in one sample were detected in 36–50% of the tested lots. Considering the provisions of integrated pest management, and the major pests and diseases of selected crops, normally three to four and exceptionally, seven to nine active ingredients with different modes of action should suffice for their effective and economic protection within four weeks before harvest.

“…Pesticides are biological or chemical substances intended for preventing, destroying, or controlling any pest that causes losses in agricultural and food production (raw materials and food), processing, storage, or marketing. Depending on their use, several types are known: fungicides (prevent the development of molds), insecticides (destroy insects), herbicides (used against weeds), and pesticides (repel or destroy rodents, nematodes, and mollusks) [ 1 , 2 ].…”

The treatment of agricultural areas with pesticides is an indispensable approach to improve crop yields and cannot be avoided in the coming decades. At the same time, significant amounts of pesticides remain in food and their ingestion causes serious damage such as neurological, gastrointestinal, and allergic reactions; cancer; and even death. However, during the fermentation processing of foods, residual amounts of pesticides are significantly reduced thanks to enzymatic degradation by the starter and accompanying microflora. This review concentrates on foods with the highest levels of pesticide residues, such as milk, yogurt, fermented vegetables (pickles, kimchi, and olives), fruit juices, grains, sourdough, and wines. The focus is on the molecular mechanisms of pesticide degradation due to the presence of specific microbial species. They contain a unique genetic pool that confers an appropriate enzymological profile to act as pesticide detoxifiers. The prospects of developing more effective biodetoxification strategies by engaging probiotic lactic acid bacteria are also discussed.

This study shows the findings about pesticide residues and the associated acute and chronic exposure risks of different fresh commodities collected from different markets located in Bursa province during 2023 winter season. For this purpose, pesticide residue levels of the collected samples were analysed with LC-MS/MS. Highest levels of insecticide and acaricide residues were detected in some lettuce, parsley, dill, carrot, pear, mandarin and banana samples and they were exceeded the maximum residue limit (MRL). The acute and the chronic exposures to pesticides were assessed by using the highest and the average redidue levels of each pesticide respectively. Highest acute exposure was calculated as acute reference dose (ARfD) exceedance rate and it was 104.27% for indoxacarb in apples, 107.06% and 137.11% for lambda-cyhalothrin in pears and mandarins, and 158.2% for phosmet in pears. For all commodity types, none of the pesticide residues displayed chronic hazard. When the cumulative long-term exposure evaluated, none of the insecticides was found to be risky for adults. The findings showed that the levels of insecticide residues on lettuce, parsley, dill, carrot, apple, pear, mandarin, orange and banana samples collected from Bursa markets in winter 2023 could not be considered as an important public health risk.
