Bee pollen; Pesticides; Automated clean-up; Risk assessment
This study evaluated the pesticide residues in commercial bee pollen samples and found different types of pesticides, including plant protection chemicals and veterinary treatments. Although pesticide concentrations exceeding the maximum residue limit were detected in some samples, the risk assessment showed that consuming these bee pollen does not pose an unacceptable risk.
Pesticide contamination in emerging foods and supplements is currently a topic of great interest. This study focused on the evaluation of pesticide residues in commercial bee pollen samples to evaluate the risk associated with their consumption. To this end, an automated clean-up method for the pesticide extracts of bee pollen was developed. An LC-MS/MS and a GC-MS/MS method were validated for the analysis of 353 pesticides in 80 bee pollen samples purchased from different countries. The results showed the presence of 77 different pesticide residues in bee pollen, including plant protection chemicals and veterinary treatments. 85 % of the samples were contaminated with pesticides and no relevant differences were found between conventional and organic samples. Pesticide concentrations exceeding the imposed MRL were found in 40 % of the samples, but the risk assessment showed that consumers are not exposed to an unacceptable risk when consuming the evaluated bee pollen.
